Security: the wireless network, please buy the wireless router security
Beijing softer (November 16, 2010, 45)

With the advent of the popularity of wireless networks and security issues, many home users concerned about the security of wireless networks, in particular the recent rub net “God card”, so a lot of home users to switch to the embrace of the cable network. In fact, in order to ensure the safety of the home wireless network must have a comprehensive security features to protect the ability of wireless router.
Calls on the wireless router security
Easier for the effect and the negligence of the user’s home wireless router to establish a wireless network intruders, the illegal intruders can use the user’s wireless network, crack wireless router device password, and invasion of privacy within the user’s computer files.
The security of the wireless router to a certain extent,HP Compaq NX7400 battery the use of a variety of security features to protect the user’s wireless network and computer. Security wireless router, in fact, the security functions had an outstanding performance compared to traditional wireless router, wireless router set security logging, advanced wireless encryption, multi-way binding function in a . With these capabilities, users can maximize avoid its own wireless network intrusion, so that legitimate users can successfully access, so use the “God card” rub family trackless into.
Optional points
Purchase security wireless router, pay attention to traditional wireless router to buy skills, have combined with the wireless network security features to choose. In the purchase, the user must pay attention to whether the product has the following features or characteristics.
A. Encryption must be
Not all products support WPA2 encryption technology,Toshiba PA3420U-1BRS battery replacement
the fragile part due to WEP and WPA encryption technology, we support the more advanced WPA2 encrypted wireless router be considered as a security product.
Many products only support WEP and WPA encryption technology, users can query whether the product through the product manual or box to support WPA2 encryption technology, the boot device into the management interface can view the encryption supported by the device through the wireless security options. Does not support WPA2 encrypted wireless router should be the first to be eliminated.
Two. IPtable function can not be less
The so-called IPtable function is able to configure various parameters for both the data communication, IP address, MAC address, port number, protocol, communication time, so that users can network communication traffic in the strict management, to avoid the illegal terminal communications. Under normal circumstances, the common products only provide the IP and MAC address binding function, and less with iptables functionality of the integrated management of IP address and MAC address. Purchase,Dell Inspiron 1464 battery
it is best to enter the product management interface, product with IPtable function.
3. Transmit power can be adjusted
Wireless network intrusion are achieved through the capture of the transmission of wireless signals, so as long as the intruder receiver do not have enough signal to automatically adjust the wireless signal transmission power of wireless router from this perspective is useful.
Provided directly on the market can not adjust the wireless router to transmit power function, but the third party firmware DD-WRT user to select a brush device of the DD-WRT firmware you can have this feature. Currently, the Linksys device can easily brush machine, followed by some of the products of the Netgear and D-Link.Compaq tc4400 battery So before buying, it is best to find products on the DD-WRT website, whether to support the brush DD-WRT firmware.
Using transmit power adjustment function, users can wireless signal is adjusted to just cover the home environment, outside device can not receive a stable signal, naturally can not be the successful completion of the work of the intrusion.
4. Preferably with WPS button
In addition to the high-level encryption, WPS automatically encrypted function is also useful for the majority of users, the so-called WPS is introduced by the WiFi Alliance’s WiFi security settings (Wi-Fi Protected Setup) standard, the main purpose of the standards were introduced in order to to solve the problem of long-standing wireless network encryption and authentication settings steps too complicated.
Today, many brands of wireless routers on the WPS button allows the user to quickly and easily encrypt the data transmitted by the wireless network to prevent the invasion of illegal users. Both to ensure the security of wireless networks, letting cryptographic operations easier.
Of course, not all wireless routers have the WPS function to determine whether a wireless router with WPS automatically encrypted, as long as the view of the shell can shell on a WPS switch button or the corresponding indicator, can determine that the equipment has WPS automatically encrypt function.

I do not know the details for a sense of things around us are not interested in, sometimes I find that, in fact, macro photography which is a very interesting shooting mode. It can truly reflect the clarity of the camera and was shooting the real side of things. Often take advantage of macro, we can put some of the plants and flowers look flat Fanfan, and even have taken a variety of creatures to life. The complete Collection of our digital photography came to talk about macro photography with a digital camera some of the methods and techniques.

Learn to use the eye when the lens

When we have our camera ready to photograph from the time, do not just see things in the viewfinder as a tool to learn your own eyes, the feeling of training with the lens,HP Compaq NX7400 battery the only way we can accurately grasp the shot we want things. Before doing macro photography, we first have to learn is to carefully observe the dedication of a variety of things, not to rush to press the shutter. The so-called macro, saying that white is very close in a long time to capture the screen, obviously, to capture the images must be the object of a certain kind of detail. So, as long as we feel that there can be some of the performance of close-ups do not give up. In fact, not difficult to find such things, as long as it is part of a body with a certain kind of features there is no problem. This feature can be a shape, color, expression, status, etc., so that the macro can be used not only to the performance of plants and flowers, all things can be.

Equipment requirements

1, the camera or lens with macro capability.Toshiba PA3420U-1BRS battery
In general, the digital camera lens is not replaced, only a few more professional digital camera. Well, for a digital camera can not replace the lens in terms of which requires the body with macro function, general English letters graphical representation of micro and small flowers. For the digital camera lens can be replaced in terms of the general requirements with the lens itself has the function of macro photography.

2, the best mode or with the central focus point of side light side light. This is because the orientation of the object to be taken less need for accurate metering for accurate exposure.

3, the camera itself is relatively light or with a tripod. When doing macro shooting as the most likely change because of the virtual hand leaving the screen, so in order to ensure a clear picture, the best selection of portable digital camera tripod, or trustworthy.

4, the focal length and magnification. The choice of focal length is a very serious issue, but also macro photography problem to be solved first, the choice of focal length and magnification should be considered together:

Flowers, still life :50-100mm or so more appropriate, magnification 1 / 8 to 1 / 4 can; insects, small animals :100-200mm or so more appropriate magnification in 1 / 4 to 1 / 2, 1 / 1 more good. For the macro lens, the most important thing is the size of the actual working distance and magnification.

5, the aperture need not be great. Do not think that there will be obvious to enlarge the aperture depth of field. In macro shooting, their depth of field will produce very clear results, it does not necessarily need a large aperture.

Shooting a few important details

1, pushed to the wide-angle end of the zoom during filming. This is not targeted at digital cameras with interchangeable lenses is the. And must use the telephoto end of traditional film camera macro contrast, digital camera macro will need to adjust to the wide-angle zoom, and then select the Macro shooting mode to shoot close objects. Only then can a more accurate and efficient.

2, note that when shooting light. Let’s talk about the light-bit key usage:

(1) shun light. Also called “positive light” refers to the direction of light projection and filming in the same direction of the light. In this light, the subject even by light, the scene is not shadows, color saturation, can show the rich color effects. However, the lack of light and dark contrast features, there is no level and dimension. I personally do not like to use this light, photos as if telling a tale, not vivid.
(2) backlighting. Also known as backlighting, light and shoot in the opposite direction,Compaq tc4400 battery to outline the contours of the brightness of the subject is also known as contour light. Structured scene under backlight lines prominent, vivid screen, shoot photos and spatial three-dimensional sense. Therefore, the best performance of the backlight in the dark against the dark background landscape, is an ideal light. We often use it to capture the silhouette, the effect is good.
(3) side light. The direction of light projection is greater than 0 degrees and take direction at less than 90 degree angle to the light, side light under the object, a good contrast between light and dark, with a three-dimensional, color reproduction is good, rich layers of film grain, while most of the 45-degree The side light is the best, because it is consistent with the visual habits of the people, is one of the most commonly used light-bit.
(4) top light. Is the subject of light from above. Top light, the scene of the horizontal illuminance is greater than vertical illuminance, the lack of intermediate level, shoot the scene, the characters seem not angry, is a less than ideal light. But for the old man, old peasant woman black eye socket and other special characters, prominent cheekbones, very expressive wrinkles Daoke.
(5) low light. Is just rising from the ground or the sun’s rays fall, mainly from the morning and evening. Low-light shoot the scene is very vivid, very angry, and this light color temperature is low, was the warm red tones, has a special color effects, is an ideal light.
(6) scattered light. Also called false Yin Tianguang line, average illuminance, light and soft, light than the small, small color in the subject no obvious projection. The light should show a better life quiet, innocent and naive girl children.

3, note that the shooting angle. First of all, photography is the direction of the camera and the subject in the horizontal plane of the relative position of the camera, that is, we usually say that the front, rear, left, right, or front, back, side. When we started taking pictures when photography is always the first choice point, is to choose the direction of photography.battery for Dell Precision M6600
Determined after determining the direction of the angle of photography. Photography has changed the direction of the screen image features and the mood will also change.

Positive Shooting:

Conducive to the performance of filming in front of the positive features of the object, can fully show the horizontal lines on the screen. Easy to be taken this positive solemn, serene atmosphere and object symmetry. Portraits, when people can see the full facial features and expressions, there is intimacy. Positive film, due to the horizontal lines of the subject easy to level with the viewfinder frame parallel to the main screen and if a very large area, they will be the main horizontal line block, there is no way to make our line of sight deep stretch. This composition will appear dull, and the lack of three-dimensional sense of space.

The back of the shooting:

The back of the shooting is the subject of being behind the camera. This direction is often used for the main characters take the picture, the main characters and the background can be integrated. Things in the background is the main object of concern to people. The back of the shooting did not attach importance to the facial expression, but it focused people’s attitude to the performance of the heart, mainly the image of language.

Is the side shooting

This refers to being left or being right. This direction applies to the performance of the main characters has a unique place or time. First, help to highlight the positive side of the outline of figures and lines. In the emotional exchange between the main characters shooting when two people can move and look lively show.

Xiece direction of shooting

This is what we usually say that the left front, right front and left rear, right rear. This film features the direction of the horizontal lines is to make the subject into a slash on the screen, so that objects produce significant changes in physical perspective, but can expand the capacity of the screen, make the picture lively. Secondly, we take the perspective that the problem is. It is the camera with the subject in the camera’s relative position on the vertical plane. Or the direction in photography from the fixed case, the camera between the subject and the relative height. Different because of the relatively high, they form a flat, Yang, overlooking the three different camera angles.

-Ping:

Is the camera and the subject in the same horizontal line to shoot. This time the subject is not easy to deformation, in particular activities-ping character scenes, people feel equal and intimate. When shooting natural scenery, the horizon of the treatment is very important. We are down to emphasize the symmetry, can the horizon in the middle position. But under normal circumstances, should avoid the case of split-screen average of the horizon, because that is the case, vision and close-range will be compressed in the middle of a line, the screen flat, dull.

Yang photo

In this case, the camera below the subject is taken up. Prominent subject in favor of imposing tall, able to grow up the tree so the scene unfolding on the screen fully. Photo by Yang close to the ground moving objects can also be used exaggerated vacated, jumping and other activities. Yang took the time people pay attention to is that fat people face, try not to compare this film.

Overhead

Camera above the subject is shot down. This perspective as if long-term perspective, the current scene from near to far from the bottom on the screen unfolds to full level. Conducive to the performance of the scene on the ground level,Price of Dell Precision M6600 battery
the number, location, etc., can give a vast and profound experience.

4, engraved note changes the depth of field inside the LCD. Performance is often a good depth of field can make a picture to life. In our viewfinder before pressing the shutter, we should always pay attention to the inside of the LCD screen to show the depth of field changes from the specific choice will be based on different aesthetic to each person identified, regardless of which do not want to screen must take into account a fuzzy shot of the main service to it.

5, as much as possible to use a tripod.

6, you can select a variety of film topics. We often see the performance of macro photography flowers and insects, fish, generally, in fact, we might try taking pictures of people, macro photography is suitable for some things.

7, a good selection of focus. When doing macro photography is the focus of most can not ignore the choice, we should focus on things that can best performance characteristics, some of the most out of color.

Many Windows services are double-edged sword, with, it might bring a lot of security risks. This article describes the ten services, suggest that you must be disabled. Windows XP services that must be prohibited

1, NetMeeting Remote Desktop Sharing

NetMeeting allows authorized users to access each other on the Sony VGP-BPS9 battery replacement network. The service for most individuals is of little value, Moreover, the opening will also bring security services, because the service will access the user name when sent in clear text to the client connected to it, hackers sniffing procedure is easy to detect these account information.

2, Universal Plug and Play Device Host

This service is provided to support Universal Plug and Play devices. The service there is a security vulnerability, a computer running this service are vulnerable to attack. As long as the attacker to a Dell Vostro 1700 battery pack Windows XP system has more than one network to send a fake UDP packets, it may cause the Windows XP host on the specified host to attack (DDoS).

Also, if the port 1900 to the system to send a UDP packet, so that “Location” field of the address points to the chargen port to another system, it is possible to make the system into an infinite loop, consume all system resources (need to install the hardware manually open).

3, Messenger

Commonly known as messenger services, computer users in the Compaq battery LAN can use it for data exchange (transmission between client and server and Alerter service messages Net Send, this service has nothing to do with Windows Messenger. If the service is stopped, Alerter messages will not be transferred.)

This is a dangerous and nasty service, Messenger service is basically used in the Dell Studio 1537 battery replacement enterprise network management, but the junk mail and spam advertising companies, and often make use of the service released pop-up ads, titled “Messenger Service.” And the service there are loopholes, MSBlast and Slammer virus is to use it to spread rapidly.

4, Terminal Services

Allows multiple users to connect and control a machine, and displayed on the remote computer desktop and applications. If you do not use Windows XP’s Remote Control feature, you can ban it.

5, Remote Registry

Enable remote users to modify registry settings on this computer. Registry can be said that the core of the system, generally do not recommend users to make changes, let alone let others remote modification, so the service is extremely dangerous.

6, Fast User Switching Compatibility

Under the multi-user applications that need to provide management assistance. Windows XP allows a computer to quickly switch between multiple users, but this IBM THINKPAD T40 battery replacement feature has a flaw, when you click on the “Start → off → fast switching”, repeated in the traditional way to enter a login user name to log , the system that is brute force, and lock all non-administrator account.

If you do not often use, you can disable the service. Or in the “Control Panel → User Accounts → Change way users log on or off” in the abolition of “Use Fast User Switching.”

7, Telnet

Allow remote users to log on to this computer and run the program, and supports various TCP / IP Telnet clients, including UNIX and Windows-based computers. Also a dangerous service, if you start, remote users can log in, access to local programs, and even can use it to modify your network settings such as ADSL Modem. Unless you are a professional or computer network without a server, or have to ban it.

8, Performance Logs And Alerts

Collection of local or remote computers based on preconfigured schedule parameters of APPLE A1078 Battery replacement performance data, and then writes the data to a log or triggers an alert. In order to prevent the remote computer search data, prohibiting it.

9, Remote Desktop Help Session Manager

If this service is stopped, Remote Assistance will be unavailable.

10, TCP / IP NetBIOS Helper

NetBIOS, under the Win 9X often use it to attack someone, do not need to file and ACER Aspire 3680 Battery pack print sharing for the users, this can also be disabled.

Most of the civilian-level digital camera with macro function, that is, without attaching any lens in the case, just gently press the macro function buttons, took pictures and SLR can capture the effect of phase comparable. SLR cameras and digital cameras under the same aperture, with a greater difference. Large aperture camera (like f2.8) obtained by the depth of field, change for the following SLR cameras may take a small aperture f11 was possible. The exposure time (shutter speed) / aperture relationship between the size of the digital SLR and the principle is the same, so trying to achieve a particular exposure, the digital camera can use faster shutter speeds, thereby holding possible. As long as own a digital camera with macro function, we can more easily be macro photography.

Following these words are some of my shooting experience and feelings, while not “professional”, but would like to give some love nature, photography-loving friends some insights.

1, according to the behavior of insects to determine time of filming. The morning sun just rose up, whether from the perspective of photography, or the habits of some insects are very good perspective of shooting time.

The gap through the tent to see the sky is already some light,Dell Vostro 1000 battery
I got up and picked up the camera, slowly pull out of the tent zipper drill, a few came in last night was a small light to attract moths fly out followed suit, they fly low, along the direction of their flight, I saw the sun above the horizon just jumped out. Thick meadow dotted with numerous wild flowers, seemingly calm, in fact, full of life, yes, this is what we dream of the best shooting time. At this time the temperature is still very low in the grass, insects are almost stationary, they have to wait after the sun rises fully to absorb the heat, the day’s activities will begin. This undoubtedly provided us with excellent photo opportunities, as long as you find them, could easily compose and shoot.

Through the night temperature, dew grass into the world, they are scattered all over the place: a wide or narrow leaves, delicate flowers, the rules of the spider’s web, as well as butterfly wings.Dell Inspiron Mini 9 Replacement battery Weak light may increase the exposure time accordingly, you should try to choose the most stable shooting position, the shutter speed is less than 1 / 20 seconds is recommended tripod shooting. The spread of the sun, like the curtain was slowly opened, when the soft and beautiful “Light” shines on the stage when the insects can not wait to start show.

A small gray moth looks down the slender grass climb the open area, there is no weed block, the sun shines on it nice and warm to him. Inadvertently, presented in front of me was a perfect picture of the nature described.

2, according to the habits of the subject,CASIO np-60 camera battery looking for shooting models. Moreover, you should understand some of the relevant knowledge.

People often say, “Splendor flowers”, in fact, like many insects visiting flowers. Various bees, flies, flower beetles, small beetles, etc., they are inseparable from the flower, can not do without this sweet food. If you do not have knowledge of certain insects, and are impossible to start looking for insects, may wish to take note of some flowers. Insects feeding on the flowers when the alert will be reduced some, we can more easily access them. Nettle this beautiful butterfly just keep tooth and nail, even though I shot at close range, it also unaware. Shooting photos of such a large color contrast, try to select the butterfly in the middle of color to the metering.

3, in the filming process, we need a discerning eye, carefully observed.

Many friends have asked me why they do not see so many insects? Indeed, the insect body size is very small, not easy to draw our attention, but also the use of “mimicry” and “protective coloring” to deal with predators, they try to integrate themselves into the surrounding environment, to our finding a greater increase challenges. However, if you are willing to spend more time and patience to find, I believe you have a very good harvest.

Show about a class is good at hiding the insects, they are always quietly lying on the grass, and the limbs stretch as far as possible to enjoy the sun. Mimics their own very self-confident, even if very close,battery for HP Compaq Business Notebook NX6140 as long as you do not touch it, it will not budge. We can devote more time to consider the composition, as far as possible Tettigonioidea long filamentous antennae and extend the limbs are taken complete. Large aperture, we still have a near perfect depth of field, you can clearly see the wings covered with vein-like pattern and that little eyes sparkle.

4, plus a little bit of luck, patience is a prerequisite for successful shooting some of the insects.

Nature photographer, especially shooting the smaller insects, careful patient is essential to find a little bit of luck will bring you surprise. Cicada species is more difficult to shoot, they either indulge in singing the high branches, or on it very far away from you, when suddenly the dense foliage away after a while rattling, almost does not give you the opportunity to shoot This time we need a little luck for help. Hot and quiet afternoon in the mountains, I am a man climbed halfway up the mountain and decided to sit down and a break. Inadvertently, found only in the ancient ginkgo tree trunk lying on the Maemi, which is about 20 centimeters away from my will,EliteBook 2730p battery and have no means of escape. Viewfinder I first look to see a cicada: a pair of stout front foot, abdomen, two mid-summer atmosphere of the tympanic membrane manufacturing sounder, and two pairs of membranous wings and strong – this is simply a masterpiece of the Creator! Shot using a large aperture, so that blur the background out of quartzite, and the cicadas who just simple and elegant harmony of colors, the picture gives a tranquil feeling. After all, luck favored by a minority, more or to test our patience. Of course, this is the fun part of nature photographers. Long-horned bee is a type of patience before they can take to the insects, they are always busy shuttling between the various flowers,EliteBook 2740w battery each flower takes time to stay very short, almost not give me a shot opportunity. I could only watch one guy who wore long tentacles flying in front of me. Fortunately, I found these guys tired to fly on the pine needles would fall a little rest, but the shooting is still difficult, they really do not waste their big eyes, little action as long as I will immediately take off. I had a pair of Dundao low pine needles waiting for the opportunity, did not think the other is nearly 3 hours, okay, the photos you want photographed, but also long-horned bees have a better understanding.

5, there will always insist on return, photography itself is not easy, insect photography even more so.

Mantis in the flowers was a big guy caught the Syrphidae, thirty-two to eat the most part. Game soon attracted to the taste of a group of greedy little fly, they keep flying around the praying mantis,price of HP Compaq Business Notebook nx8220 battery a rush to have the opportunity to enjoy a feast of doing nothing, and even the guy’s mouth fell lick mantis Fresh juice. The face of these nasty invaders, the mighty mantis no way. Large aperture virtual body almost out of mantis, mantis highlights on the eyes and firmly clamped to capture enough prey. The surrounding environment is complex, try to choose the vertical composition make mantis fill the screen, so that subject more clear.

A good photograph should first of Insect Ecology is a vivid picture. We normally see a lot of common insects, in fact, can shoot a good picture. Many people think that good photos, either bloody strangulation scene, or the type is very rare, and I think a picture is vivid ecosystem is essential.

Insects in their little world to complete a short self-serving life course: the pursuit of happiness, or spouse; or resort to force to prepare for hunting; or a big mouth and chewing on delicious food. All of these are happening around us, the real and very common. However, as long as the insect itself, With love, to understand their passion for life, we can use their own cameras to record the insects but usually brilliant, true and no shortage of lively moments, to use your own photos to give insects “personality”!

A little bit about the good insect photography tips: During the shoot, no matter how careful we are, in fact, are more or less disturb the lives of insects. Ants, aphids, animal husbandry, accelerated the pace of panic, a small beetle reduced to less than one fell to the grass, the boat kept shaking larva’s body hung upside down, leafhoppers quickly flash back to the leaves, enough to capture mantis raised, eyes dead death staring at you … … there are some masters of mimicry, camouflage their confidence,Compaq Presario v6000 Battery such as Tettigonioidea or some geometrid moth larvae, even if we close contact, they do not hit them, they would have maintained the original Some attitude, motionless, and you think it afraid of you, you do not disturb it, it is not true, just that they chew the leaves are still shoveling or cleaning the body comfortably, as you come, all this stopped. Therefore, we should bring them to minimize the pressure and panic. I usually approach them carefully, dodging the subject after one or two I would consider giving up photography. In fact, after all, looking in nature we can not have no effect on the ecosystem, it is important that there should be moderate.

World Cup on your PC – Free internet TV software a complete application testing
Fork out 20, 21 … in the calendar the days of May I one by one, watching day by day, June 9 near, my blood started flowing, the excitement I have some confusion. Every day wondering how can each event. A day off? Superior long approval: during the World Cup refused to leave; resignation can ensure foolproof, but after the World Cup? Wrong, wrong! In me negate After, the mood is even more confusion.
The above symptoms are fans suffering from the typical World Cup anxiety disorders, look at the recipe before you are not impulsive and wrong things, allows you to remain calm in this hot summer. Solemnly prompt:
If you have doubt, we will answer you! Question 1: I in the company to work overtime, encountered the World Cup launch to go where to look?
Question 2: I am a student, the bedroom do not have a TV, how in order to understand the fastest World Cup? Question 3: If you miss a tournament, how to make up for the World Cup did not see?
Answer: Using a P2P network television software, and it’s free! Online to watch the World Cup the best choice – P2P Internet TV
Today, the growing popularity of broadband network to the video age. HTTP downloads, we have had FTP download, with the P2P download, the most gratifying is that network television is more and more mature.battery for Toshiba PA3457U-1BRS battery
After several years of development, the network television has been far beyond the mere “television program” category, to the point of an incredible – with a simple software, we can watch as many as hundreds of TV channels (for a fee, even up to hundreds of TV channels); the same time, we can also see video of popular sporting events or live online through the Internet TV software. Enjoy these a prerequisite, just a computer +512 Kbps (and above) bandwidth Internet access. In this hot summer, the World Cup to snatch the focus of major network TV software. The crazy wave of network television is a technology that contributed to P2P, it greatly reduces the dependence of the video server. P2P TV use, “Many hands make light” of this approach with traditional shared network television to see the more you do not smooth “On the contrary, a P2P network television programs is to see more people, it is the more likely connection to watch, the more smooth! This should not be too high bandwidth, regardless of geography, Many hands make light the flame high P2P TV, a produce crazy development, when the finals of the 2005 Super Girl, the use of P2P network television software in a single paragraph / to watch more than 500,000 in the number of !
If your computer inside a P2P network television software, then, quickly download and install a greet you will be rich resources to make you surprised. Free P2P network television Triwizard – PPStream, PPLive, QQ Live
P2P TV family members, but as crazy, its elimination has become very cruel. Content updates more quickly, more stable, more users, you more red, and vice versa with your people on less and less. The crazy expansion and brutal elimination of the birth of the free P2P network television software, PPStream, PPLive, and QQ live (refer to the latest version). Three software updates faster, the interface have done a beautiful atmosphere, the use of very stable software, peripheral support and website support are doing better, more important, their information content is very rich, popular also very busy, so in order to become a versatile P2P TV software is the top three!
I believe there will be a lot of people ask: three software, who is No. 1? P2P era, No.1 often is the last survivor. In this test, we tested a variety of ways appraisal, if you read carefully, you will find the answer! Tip:
P2P TV for PC hardware requirements are not high, the processor will be able to get about 1 GHz. It is worth noting, however, different software performance there will be some differences in different network environments, for example, different service providers (Telecom, China Netcom, China Unicom, CRC, mobile, length and width, etc.), different access methods (the external network IP, and LAN). Our test mainly residential broadband telecommunications as a benchmark (the extranet independent IP), combined with China Mobile fiber-optic access + LAN network within the network test considerations. Test platform:
CPU: Celeron 1GHz motherboard: i815-
Memory: 128MB x 2 SDRAM, graphics card: GeForce FX5700
Hard Drive: Seagate Barracuda 7200.7 60GB operating system: Windows 2000 Professional + SP4,
Test time: 20:30 (when the Internet during the peak period, and network TV is relatively smooth) test project
The test items for the seven, namely: (1) video and audio resources
The richness of the 2 sports section. Play fluency (Multi-network environment considerations)
4.CPU occupied (Hunan TV for the test channel) 5. Best quality sources for playback
The maximum network bandwidth consumption (using NetMeter as the test basis) 7. Characteristics of the design (software user-friendly, functional features and characteristics)
Test results using the asterisk system, in order to obtain intuitive results. At the same time, we will each software performance to be described in detail. We did not introduce the initialization time (ie, a program selected from the operator / channels start to show a pictureHP Probook 4720s battery / sound and start normal playback time) test, because different software may differ from the heat for the same program / channel, and different network environment, different times, will this time have an impact, even if the same program of the same software at the same time connected, time will be quite different.
Mature PPStream version: 1.0.1.182
Download: PPStream file:
PPStream (Figure 1) the development is now very mature, relatively prosperous popularity. Moreover, many large network of media relations of cooperation. The software not only have a single player, and support web page playback, web site development is relatively high, the site content is also very rich, electronic program guide, channel introduction and communities. Another major component of the site is the program’s website directly playback. It is worth noting that it comes with a CCTV broadband part ( on this page, you can watch most of the channels of CCTV.
Figure 1 the use and testing of PPStream with nearly 100 of the 10 categories of programs / channels / columns, we should say, the player with the TV channels is not too much, but the high popularity of Hunan Satellite TV, CCTV5 and so contains, including PPStream with a lot of fashion channels such as Channel [V], the French fashion, HBO, home theater, but also with a lot of games channel. PPStream also with thematic repertoire and channels, such as animation and cartoon column Crayon, Conan series; television theater there are the “Wulin”, “from which stars” (a popular Korean) ; movie channels, there are a series of “Andy Lau”, “Jet Li” series. The program list is usually a current hit movies such as “Jasmine”, “Barber of Seville”.
PPStream program classification part of the world of sports, In addition to the the CCTV5 outside, and also includes a 4-channel / part, not too rich, I hope to begin broadcasting the World Cup will increase the appropriate channels and columns. Telecom residential broadband environment the PPStream of program playback is very smooth. However, we also noted in non-hot periods, sometimes popular channels (such as Hunan Satellite TV), the connection will be a bit hard. In China’s mobile network (test machine for the company intranet), PPStream program connection, especially in non-hotspot time TV channels to connect and play is a bit hard (CCTV5 exception).
The PPStream play Hunan Satellite TV CPU utilization of 30% to 48%. Please note that this is a 1GHz Celeron processor, if it is a 3GHz P4, the occupancy rate of 5% to 13%. PPStream most of the video quality (especially in real-time TV channels, but this is a common problem of the P2P network television programs), although the effect of the column plays live TV channels, but still more reluctant to watch in 100% size the effect is pretty good, but full-screen under less than ideal.
Since network television, will inevitably involve the problem of network bandwidth. We mentioned earlier, the PPStream of program quality and not very good, this is actually also illustrates another problem: the PPStream The program bit rate low, taking up little network bandwidth. In addition, PPStream the cobwebs network structure, the user is connected to the network, download, while also immediately for other users to upload data with upload / download ratio (Figure 2).
Figure 2 Note the UL upload download and DL numerical differences,HP EliteBook 2760P battery and the graph at the top left MAX value. PPStream UL / DL ratio, but also takes little network bandwidth. PPStream channel list of the main interface area of ​​each channel / program viewership data, we can according to this data to determine the program’s popularity, and fluency (P2P Internet TV is of course the more popular the more fluent). PPStream also provides a skin replacement, shortcut keys automatically prompt functionality. In addition, PPStream with the current program thumbnail screen to obtain, but also with the electronic program guide, but no specific timing, the specific timing on a web page to see (see Figure 1).
Powerhouse PPLive version: 1.2.21 (1.1.0.8) version better than PPStream. Korean effect is very good, bright color screen, clear image, 1024 × 768 resolution display, full screen viewing. Three software PPLive program playback quality is the best. Playback quality good premise is that new sources for quality and security, code rate, PPLive is the – most of its drama series, TV specials bit rate usually reached a nominal bit rate, so relatively PPStream, PPLive transfer program will take up more bandwidth. NetMeter flow analysis, PPLive mainly early in the connection to download the main, and sometimes even break the 1MB / s. In the video to normal playback after a few minutes, upload / download ratio balanced, the final upload will gradually than downloads (Figure 5).
Figure 5 PPLive network bandwidth requirements than the PPStream, but in the end to upload will be far greater than the downloads
Different from those the PPStream interface of the publicity, the main interface of PPLive is more introverted, very clean and fresh, while the list of resources is also very concise, but once you open the list of resource layer, to greet you will be rich in natural resources, from that point. The PPLive gives a more mature feel. In addition to the LAN sharing watch collection program, PPLive with program Reduo display, support for real-time program bitrate display, but also with a very handy program from the program from a very detailed, including a specific timetable. The most dynamic QQ Live
Version Number: Version 3.1yback. However, it is still under the LAN performance is not satisfactory. QQ live play fluency in non-hotspot time remains to be strengthened, the network data transmission peaks and valleys, and sometimes interrupted. QQ Live interface is very gorgeous atmosphere, and a list of resources for each program resources have the LOGO, very beautiful. , QQ live three software CPU utilization, playback CPU utilization of 32% to 75%. P4 3GHz system CPU utilization to reach 28% of system hardware requirements are relatively high.
QQ live TV channel effects and the two software is insignificant, but more general column show / movie / series playback, can not achieve full screen playback is only suitable for the window to watch live (QQ default player window. in the default window size, have been able to meet the needs and aspirations). QQ broadcast network bandwidth is quite large in the hot hours to watch the hot show, Hunan Satellite TV to 8:30 pm watch for example, QQ live in to watch the first three minutes to download, rate more than 60KB / s ~ 400KB / s, and sometimes you can jump up to 1MB / s upload speed is low, which would give the server imposes a heavy burden. Play five minutes later, the uploading and downloading to stabilize, the upload speed than download speed. But still a problem: The download speed of long-term more than 150KB / s, this 150KB / s all video files, code, has meant that the programs of more than 1Mbps bitrate, however the quality of programs …… (Figure 7).
Figure 7 downlink bandwidth consumption big regret at the QQ live, if the network environment is not ideal, would be more difficult to use QQ live
If the characteristics of QQ live feature is very distinctive and outstanding, it’s beautiful interface, and the introduction of a number of “channels” and “Online” concept (Figure 8).
Figure 8 QQ Live provides a graphical interface, and the channel number and the total line number prompt QQ live another major feature is to provide a model community watch programs with friends can chat while watching, greatly interactive and fun enhanced.
The three mainstream free internet TV software test results after previous use of testing, here we use a table of the three software results show it to everyone, so that everyone at a glance.
Can be seen from our testing table, each software has its own characteristics. We can select a suitable software according to our test results, combined with their own situation. Here to remind you that not all network environment can now get Internet TV, which not only software, and sources for the problem, the network bandwidth and stability problems. We introduce three “large and strong P2P Internet TV software is not the best in every respect, for example, some companies in the LAN environment, the small head of the boiling point of network television is often a good software, although It features simple, primitive interface, program quality is not outstanding, but it can be fast and stable connection and play.
Six wonderful technology Fun TV network we must first sharpen his tools. Us to understand the characteristics of a variety of network television software, we are also familiar with a variety of skills watching network TV, to make them for my own use, and lay a good foundation to enjoy the World Cup.
A P2P TV is more stable and efficient when we enjoy these P2P TV in Windows XP SP2 operating system, will often find that the playback screen is not smooth, and for this reason behind the fact, with Windows XP SP2 on the system of concurrent threads number restrictions. Therefore, we remove this restriction, can improve the playback quality of the P2P network television.
Step 1: in order to open the “Tools → Options” command in the the PPStream main menu, click the XP SP2 patch “option in the dialog box appears, press the” Download Patch “button in the page that opens. Step 2: Run the downloaded patch file in the “current limit”, enter the higher value of the thread, click the “patch” button. Out of the “Windows File Protection dialog box, click the” Cancel “button, and then click the next dialog box” Yes “button.
So after you restart the computer, you can easily breakthrough SP2, simultaneous threads, limit P2P TV programs, play smoother.Thinkpad T400 Battery
(B) the collection of exciting channels
P2P TV tool to watch network TV, often due to poor network connectivity, and other reasons can not refresh the channel list, so that you can not switch to their regular sports channels to watch the event live. In fact, we just before such a failure in advance will often watch the channel into the “treasure chest”, you can easily solve this problem. This PPLive example.
Step 1: Open the the PPLive main interface, expand the right side of the page, click the “channel list” tab, select their favorite TV channel, click the right mouse button, select “Favorite” context menu command, You can add selected channels to the “My Favorites” (Figure 1).
Figure 1 Step 2: When the channel list can not be refreshed again, simply open the “My Favorites” section, then select the favorite channels, so that you can direct broadcasting of television programs. Also available in PPStream channel collection method Similarly, do not do more introduced.
Three. Television program broadcast regularly during the World Cup, when we indulge in activities such as online chat, they may miss an important football match broadcast time. In order for the exciting events pass is no longer with us, it may be with the the PPStream The timing play function.
Step 1: Open the the PPStream main interface, select the appropriate channel name in the left side of the channel list, right-click and select “Copy URL” context menu command. Step 2: in order to open the main program menu “Tools → timing” command in the open “time” dialog box, check the “timing” option. Set a good play time in the right side of the drop-down list, select the “broadcast channel” input channels just copy the address in the “Channel URL”, click “OK” button (Figure 2).
Figure 2 PPStream running in the background, to set time, then will play automatically set the channel program, so we are no longer the omission of any important events.
Smooth appreciate the bilingual TV program in the use of P2P TV broadcasting of television programs, we often see some of the bilingual television program. When two languages ​​are intertwined play, it would seriously affect the playback.
At this point, we open the system the lower right corner of the taskbar speaker icon in the open “Volume Control” window, left or right, drag the slider on the “balance” area. So you can adjust the size of the volume of the left and right channels, solve bilingual playback problems (Figure 3).
Figure 3 In addition, You can also use the default player Windows Media Player for TV playback, then select the main menu View → Enhancements → graphic equalizer, about to adjust the playback region appears below the “balance” area balance. V. LAN play live television
P2P TV will take up some bandwidth, LAN users to watch the game and all P2P TV, you will naturally let the entire local area network speeds become quite slow. Many P2P networks provide a local area network sharing capabilities, with the help of this feature, we can use the LAN a host of television broadcast, so we do not needlessly consume network resources, this is still PPStream example.
Step 1: Open the main program interface, in order to open the main menu “Tools → Options” command. In the dialog box that opens, select “LAN sharing” in the right list of options. Step 2: In Playback HTTP address binding region equipped with the final version of the machine’s IP address.
Corresponding to the asx file will be generated when the http host when playing online TV, PPStream installation path folder, other users can share the contents of the http file folder, you can click on to the ASX file to play TV show. Similarly, if the media file output path “area, click the” Browse “button, select any folder in the machine, check the” Share this folder “option, click” OK “button.
Other users open the media player, click the player’s “Open URL” command in the dialog box that appears, click “Browse” button, select the “My Network Places” to live the name of the computer, you can see the shared ASX file. Double-click the file, you can make use of it using the MMS protocol to play the stream information. Tip: If you use the above method is simple enough, can also PPStream player window, click the right mouse button, select the default player to play in the context menu command. When you open the default player and play content, select “File → Properties command to obtain the HTTP address. Finally, to obtain the address to send to other users within the LAN, you can use the address in the media player to open the appropriate television content.
Recording network TV sometimes, we also intend to slowly sipping the scene broadcast of the game, then the best way is to live TV recording to local hard disk. Recording network TV is very simple, through third-party tool, dubbed “P2P TV recorder” tool may wish to use this, it can record PPLive, PPStream, SopCast is a variety of P2P TV video contents.
Step 1: First, in accordance with the above method to obtain the address of play the file, then open the main interface of “P2P TV recorder, select File → increase in the P2P TV” command. Step 2: In the pop-up dialog box, click the “increase channel” tab, enter in the “URL” column just access streaming media address in the “File” section in the custom file name, click “OK” button Return to the main interface.
Step 3: Select the channel you just added, click “record” button, we can find a window file capacity, which show that network TV is currently recording. Who intend to interrupt the recording of network television, simply click the “Stop” button. When recording is completed, we are able to network TV recorded files, found in the specified folder so you can repeatedly enjoy recorded TV.
Internet TV fault solution Q: Why are Huaping broadcast network television?
A: When this happens, we have the following methods can be addressed: First, make sure their system’s media player for Windows Media Player 9 or later. If the problem still have not resolved, then we have the ATI graphics card to re-set. Open system “Display Properties” dialog box, enter the point level of the Settings page “Advanced” button, and then cancel the “WMA to accelerate the check can be.
Either ATI cards also the the Huaping problem, you can uninstall the original driver and install the latest version of the driver to be addressed. Q: When using P2P watching television, often prompted to play ASX failed “, how to solve?
A: ASX file streaming media information to redirect the browser to ASX content delivery to the media player Windows Media Player, media player to open the streaming media on the specified location according to the ASX file information with the corresponding agreement documents. The reason why the playback failure, mainly because Windows Media Player does not correlate with the ASX file format. We can open the Windows Media Player, in order to open the “Tools → Options → File Types”, select one of the ASF, ASX, options or click the “Select All” button.
Q: When the network buffer to 100%, but the picture and sound, I ask why? A: this happens because a large did not match the media player to upgrade to the latest version. In most cases, the use of P2P TV tool to broadcast television programs need Windows media player 9 and Realplayer more than 10 versions of Media Player installed on your system.
Q: I used the campus network to the Internet, other students can use normal P2P to watch TV programs, but I can not use it, always a buffer 0, 0, connecting the number 0, how the solve this problem ? A: The reason for this problem is mostly related with the network firewall settings. Firewall access rules, we can set these P2P TV tool allows access to the network. It is not, and can also turn off the network firewall.
Second, change the port number in network television, for example, in the PPlive this tool, we can turn open the “Control → Settings” command in the page that opens, click the “Network Settings” button, then click the “random port button to change the TCP and UDP port numbers can be.

Consumer DC Disadvantages:

First, consumer digital cameras and digital SLR cameras compared to when shooting portraits where there will be several of the more negative, we must be clear.
1. The CCD area is relatively small, shallow depth of field is difficult to get good results.
2. Shutter delay is relatively long, unlike the instant digital SLR is easier to catch the facial expression, is not conducive to catch the beat.
3. The camera does not provide a higher ISO options, or at high ISO,compaq presario v3000 battery
the noise is relatively high to screen the other rough.
However, the use of consumer DC to shoot portraits, but also not a place without incident, there is no advantages.

DC consumer advantages:

First of all, DC in the shot and consumer LCD display can be observed directly the result of preview to the film, brightness distribution at a glance, can enhance the success rate of shooting, will increase the fun of shooting, for starters, more easy to use.
Another consumer generally small size and weight of DC light,HP EliteBook 6930p Replacement battery relatively easy to carry on, go out shooting, especially in crowded places would not like to swagger like the digital SLR, scary, not easy when the photographed was found that the success rate of shooting naturally be increased.
Second, the consumer DC Although there are relatively deep depth of field defects, but from another perspective, in some characters and scenes are clearly needed, or to show the relative relationship of the time people, but will take advantage of.
Finally, the consumer benefits of DC of course, is its relatively low price, the move is over a million compared to the digital SLR is really a lot cheaper!

Beginners when shooting portraits, often complain about their gear, wait for DC to throw away the hands of the consumer in exchange for a digital SLR, shooting to get better and faster operational efficiency. However, the consumer can not make a good DC does not necessarily work, we have described above consumer DC also has its advantages, more emphasis on other Portrait photography is the charm and feel of the characters, but these are not good or bad depends on the equipment, but on the characters and the communication and co-photographer, depending on the time of the shooting situation.

Unless such a dynamic fashion show class performance, due to the harsh environment the stage scene, have to rely on the superior performance of equipment, we ordinary people in the shooting, as long as we feel, lots of pictures,price of ACER Aspire 5732Z battery even with an ordinary consumer DC also can photograph a lot of good photos.

You have set a correct view of it? With the right perspective, the following us to explain some basic knowledge and skills.

One. To maintain the stability of the camera

Many beginners did not agree with this point, no heart, the result pictures are often blurred in the case, keep the stability of the camera is to obtain a necessary condition for a clear picture, photos are not clear, even if you use light on how exquisite, how rigorous composition, obtained only a scrap piece.

Can be used to maintain the stability of the camera tripod, tripod shooting but the lack of flexibility, in addition to night shooting, we are rarely used. To maintain the stability of the camera there are some skills,NIKON en-el5 camera battery first of all, to steady your camera, the other in the do first take a deep breath before pressing the shutter, and then release the shutter until the breath until this method is very useful, can effectively reduce tremor the situation is the auto show in the following photographs, although the lighting is bad, but because of the method used or to maintain a relatively good stability.

Some consumer now has anti-shake function of DC, such as Panasonic FZ10 and the FX5, Canon S1IS, Minolta A1 and other cameras, and their anti-shake performance can help you effectively reduce camera shake.

II. Exposure

Accurate exposure is the most difficult to master photography one of the factors is the key to success photos.

Fortunately, digital cameras with automatic metering functions, and generally very accurate metering, DC, in most cases are able to obtain accurate exposure photographs. However, it is worth noting in some cases, such as the time when the light is relatively strong, we must consider a partial picture may have exposed the phenomenon, because in most cases people affected by the degree of illumination is not uniform, there are always some dark places which is lighter, more general use of the average DC metering method is based on the image brightness of each region the average of the exposure, which is why some beginners photos will appear overexposed because,Dell Inspiron 9400 laptop battery like the picture below is too strong and caused the light of local overexposure of the image.

Encountered such a situation, we can not rather than the principle of less exposure, because even if underexposed pictures in the computer can also make an appropriate adjustment, on the contrary if the photo had been exposed is difficult to save.

Rather not have the exposure control due to the camera’s exposure compensation can be achieved, there are some other features the camera also has a spot metering, spot metering to master the techniques are easier to obtain accurate exposure photos, but Spot is not easy to master the skills , but will also fix overexposed photos of serious or serious the situation due to exposure, where the author suggests that beginners are strong in the face of light, proper adjustment of the negative exposure compensation to avoid overexposure of the situation.

III. Depth of field

Depth of field can blur the background picture of the prominent figures of the main very good, but the digital camera CCD sensor size is too small, usually between 1/2.7 inch to 1/1.7 inches,battery for TOSHIBA PA3399U-1BAS even with large aperture is also difficult to obtain the virtual depth of field . However, we do not forget about the depth of field in addition with the aperture, the camera’s focal length can also affect the depth of field, focal length the more they can get shallow depth of field, if your hand is 10 or 12 times the big zoom DC, then To obtain a good depth of field is not a difficult task, of course, many consumer DC are only 3 times zoom function, then you can select the background taken place relatively open, so people have enough space for the rear, and then with the telephoto-shot digital camera This can also get good results, the following is the king FZ10 telephoto pictures taken, you see, the DC consumer can also get satisfactory results it!

  
  
Reach the pleasure – the touch screen DC, DV purchase
To the bank teller, touch screen Teller Machine; to tourist attractions to visit, touch screen computers explanation; smart phones are mostly equipped with a touch of handwriting features; to mention digital imaging products, major manufacturers have been in the main touch-screen design and innovative direction , so that consumers see, touch screen technology is more widely applied.
Since June 1999 the world’s first touch-finder screen Sony DCR-PC3 since the advent of the touch screen has become a standard Sony DV. Convenient mode of operation, the resulting clean and fresh man-machine interface, exquisite and delicate delicate shape, has become the Sony DV a sign of selling points. Since then, the digital camera Kodak EasyShare-One, The E510 BenQ digital camera Panasonic GS150 and other touchscreen-based forge new products have appeared on the market, into the focus of attention. All indications that the large-screen LCD + touch technology is bound to slowly popular in DC, DV.
Mainly resistive mechanical field touch touch technology works mainstream touch, capacitive touch, several of the surface acoustic wave touch. Resistive touch screen quality and stability, more adaptable and occupy the largest share of the market. DV viewfinder screen mode, for example, the touch control is to locate the set according to the finger-touch icon or menu position.
Touch LCD viewfinder screen by the touch detection parts and touch screen controller,battery Toshiba PA3465U-1BRS touch detection parts are installed in front of the viewfinder screen, this sensor the user touches the coordinate evacuation to receive the touch screen controller from the controller to accept the coordinates of the location information transfer to the main chip, in order to achieve a touch operation.
The working principle of resistive touch screen touch screen evolution
From the earliest 1.2 inches, 1.5 inches to 2.0 inches, 2.5 inches and then to the Sony T series, and even the Casio Z57′s 2.7-inch viewfinder screen evolutionary trend has continued unabated. With the Kodak EasyShare-One and Sony N1′s sparkling debut, digital imaging products 3.0 viewfinder screen era has been almost certain.HP G65 battery Consumer demand for pleasing a large LCD screen is urgent to reduce the mechanical button on the touch screen is destined to become very popular. Needed green leaves with red flowers, the touch-screen machines (DC), still in its infancy, however, the benefits of touch screen is not only good-looking, but the viewfinder, browse to upgrade until the late editor of the comprehensive experience .

I do not know the details for a sense of things around us are not interested in, sometimes I find that, in fact, macro photography which is a very interesting shooting mode. It

can truly reflect the clarity of the camera and was shooting the real side of things. Often take advantage of macro, we can put some of the plants and flowers look flat Fanfan,

and even have taken a variety of creatures to life. The complete Collection of our digital photography came to talk about macro photography with a digital camera some of the

methods and techniques.
Learn to use the eye when the lens
When we have our camera ready to photograph from the time, do not just see things in the viewfinder as a tool to learn your own eyes,IBM ThinkPad R60 battery the feeling of training with the lens, the

only way we can accurately grasp the shot we want things. Before doing macro photography, we first have to learn is to carefully observe the dedication of a variety of things,

not to rush to press the shutter. The so-called macro, saying that white is very close in a long time to capture the screen, obviously, to capture the images must be the object

of a certain kind of detail. So, as long as we feel that there can be some of the performance of close-ups do not give up. In fact, not difficult to find such things, as long

as it is part of a body with a certain kind of features there is no problem. This feature can be a shape, color, expression, status, etc., so that the macro can be used not

only to the performance of plants and flowers, all things can be.
Equipment requirements
1, the camera or lens with macro capability. In general, the digital camera lens is not replaced, only a few more professional digital camera. Well, for a digital camera can

not replace the lens in terms of which requires the body with macro function, general English letters graphical representation of micro and small flowers. For the digital

camera lens can be replaced in terms of the general requirements with the lens itself has the function of macro photography.
2, the best mode or with the central focus point of side light side light.ACER Aspire 5738G Replacement battery This is because the orientation of the object to be taken less need for accurate metering for

accurate exposure.
3, the camera itself is relatively light or with a tripod. When doing macro shooting as the most likely change because of the virtual hand leaving the screen, so in order to

ensure a clear picture, the best selection of portable digital camera tripod, or trustworthy.
4, the focal length and magnification. The choice of focal length is a very serious issue, but also macro photography problem to be solved first, the choice of focal length and

magnification should be considered together:
Flowers, still life :50-100mm or so more appropriate, magnification 1 / 8 to 1 / 4 can; insects, small animals :100-200mm or so more appropriate magnification in 1 / 4 to 1 /

2, 1 / 1 more good. For the macro lens, the most important thing is the size of the actual working distance and magnification.
5, the aperture need not be great. Do not think that there will be obvious to enlarge the aperture depth of field. In macro shooting, their depth of field will produce very

clear results, it does not necessarily need a large aperture.Dell Inspiron 1420 laptop battery
Shooting a few important details
1, pushed to the wide-angle end of the zoom during filming. This is not targeted at digital cameras with interchangeable lenses is the. And must use the telephoto end of

traditional film camera macro contrast, digital camera macro will need to adjust to the wide-angle zoom, and then select the Macro shooting mode to shoot close objects. Only

then can a more accurate and efficient.
2, note that when shooting light. Let’s talk about the light-bit key usage:
(1) shun light. Also called “positive light” refers to the direction of light projection and filming in the same direction of the light. In this light, the subject even by

light, the scene is not shadows, color saturation, can show the rich color effects. However, the lack of light and dark contrast features, there is no level and dimension. I

personally do not like to use this light, photos as if telling a tale, not vivid.battery for JVC bn-v114
(2) backlighting. Also known as backlighting, light and shoot in the opposite direction, to outline the contours of the brightness of the subject is also known as contour

light. Structured scene under backlight lines prominent, vivid screen, shoot photos and spatial three-dimensional sense. Therefore, the best performance of the backlight in the

dark against the dark background landscape, is an ideal light. We often use it to capture the silhouette, the effect is good.
(3) side light. The direction of light projection is greater than 0 degrees and take direction at less than 90 degree angle to the light, side light under the object, a good

contrast between light and dark, with a three-dimensional, color reproduction is good, rich layers of film grain, while most of the 45-degree The side light is the best,

because it is consistent with the visual habits of the people, is one of the most commonly used light-bit.
(4) top light. Is the subject of light from above. Top light, the scene of the horizontal illuminance is greater than vertical illuminance, the lack of intermediate level,

shoot the scene, the characters seem not angry, is a less than ideal light. But for the old man, old peasant woman black eye socket and other special characters, prominent

cheekbones, very expressive wrinkles Daoke.
(5) low light. Is just rising from the ground or the sun’s rays fall, mainly from the morning and evening. Low-light shoot the scene is very vivid, very angry, and this light

color temperature is low, was the warm red tones, has a special color effects, is an ideal light.
(6) scattered light. Also called false Yin Tianguang line, average illuminance, light and soft, light than the small, small color in the subject no obvious projection. The

light should show a better life quiet, innocent and naive girl children.
3, note that the shooting angle. First of all, photography is the direction of the camera and the subject in the horizontal plane of the relative position of the camera, that

is, we usually say that the front, rear, left, right, or front, back, side. When we started taking pictures when photography is always the first choice point, is to choose the

direction of photography. Determined after determining the direction of the angle of photography. Photography has changed the direction of the screen image features and the

mood will also change.
Positive Shooting:
Conducive to the performance of filming in front of the positive features of the object, can fully show the horizontal lines on the screen. Easy to be taken this positive

solemn, serene atmosphere and object symmetry. Portraits, when people can see the full facial features and expressions, there is intimacy. Positive film, due to the horizontal

lines of the subject easy to level with the viewfinder frame parallel to the main screen and if a very large area, they will be the main horizontal line block, there is no way

to make our line of sight deep stretch. This composition will appear dull, and the lack of three-dimensional sense of space.
The back of the shooting:
The back of the shooting is the subject of being behind the camera. This direction is often used for the main characters take the picture, the main characters and the

background can be integrated. Things in the background is the main object of concern to people. The back of the shooting did not attach importance to the facial expression, but

it focused people’s attitude to the performance of the heart,price of Dell INSPIRON 2500 battery mainly the image of language.
Is the side shooting
This refers to being left or being right. This direction applies to the performance of the main characters has a unique place or time. First, help to highlight the positive

side of the outline of figures and lines. In the emotional exchange between the main characters shooting when two people can move and look lively show.
Xiece direction of shooting
This is what we usually say that the left front, right front and left rear, right rear. This film features the direction of the horizontal lines is to make the subject into a

slash on the screen, so that objects produce significant changes in physical perspective, but can expand the capacity of the screen, make the picture lively. Secondly, we take

the perspective that the problem is. It is the camera with the subject in the camera’s relative position on the vertical plane. Or the direction in photography from the fixed

case, the camera between the subject and the relative height. Different because of the relatively high, they form a flat, Yang, overlooking the three different camera angles.
-Ping:
Is the camera and the subject in the same horizontal line to shoot. This time the subject is not easy to deformation, in particular activities-ping character scenes, people

feel equal and intimate. When shooting natural scenery, the horizon of the treatment is very important. We are down to emphasize the symmetry, can the horizon in the middle

position. But under normal circumstances, should avoid the case of split-screen average of the horizon, because that is the case, vision and close-range will be compressed in

the middle of a line, the screen flat, dull.
Yang photo
In this case, the camera below the subject is taken up. Prominent subject in favor of imposing tall, able to grow up the tree so the scene unfolding on the screen fully. Photo

by Yang close to the ground moving objects can also be used exaggerated vacated, jumping and other activities. Yang took the time people pay attention to is that fat people

face, try not to compare this film.
Overhead
Camera above the subject is shot down. This perspective as if long-term perspective, the current scene from near to far from the bottom on the screen unfolds to full level.

Conducive to the performance of the scene on the ground level, the number, location, etc., can give a vast and profound experience.
4, engraved note changes the depth of field inside the LCD.price of Dell Inspiron 9400 battery Performance is often a good depth of field can make a picture to life. In our viewfinder before pressing the

shutter, we should always pay attention to the inside of the LCD screen to show the depth of field changes from the specific choice will be based on different aesthetic to each

person identified, regardless of which do not want to screen must take into account a fuzzy shot of the main service to it.
5, as much as possible to use a tripod.
6, you can select a variety of film topics. We often see the performance of macro photography flowers and insects, fish, generally, in fact, we might try taking pictures of

people, macro photography is suitable for some things.
7, a good selection of focus. When doing macro photography is the focus of most can not ignore the choice, we should focus on things that can best performance characteristics,

some of the most out of color.

Second, the record of the activities of students

Students will graduate, and I feel sure will be a bit special, this time in the dorm room to shoot some content, such as students in order books, clothes, gifts for graduation. This is the first scene of the story,TOSHIBA PA3457U-1BRS Replacement battery do not forget the film Oh!

There are also libraries, canteens, quiet road, a broad field, and so lived experiment where these places should be taken down.

Fourth, the classroom shooting

From now on no longer and the students and teachers spent in the classroom. If the time to come to a halt just fine. Shooting to scan the whole class first, then shooting the classroom of the brand, very memorable. You can prepare in advance so that students seated, shooting the scene of what they read and write. At this time shooting to note that if standing in the corridor to shoot the classroom situation, it is prone to backlight situation, or choose the location of the window to shoot it.

For the teacher a goodbye to the last lesson, the teacher what to say it? Photographed Come on, let the teacher’s parting words always in mind. Then pay attention, if not to occupy a favorable position, the situation may appear backlit.

When they close, with the pace of the frequency of mobile cameras.

First, the whole hall with wide-angle shooting situations, allowing people to understand the whole process, while not easy because the hand shake shaking leaving the entire screen appears. After then zoom to the familiar figure closer to the students, then you need to open the electronic image stabilization function.

Do not always when shooting them in the same camera angles, so the whole image will change due to the lack of people feel monotonous, so it should be in the range of environmental conditions as often as possible to allow the change to take place, so much easier After shooting a masterpiece of editing a content-rich, if you want to change the angle, should be taken on the aisle or against the wall, it is a good picture of stability.

During the shooting, usually by way of documentary filmmaking, so the whole process of the film would seem tedious, lacking vivid picture content. Then we might come to a impromptu interview to make the students talk about the mood. Before shooting the best of those interviewed make a simple preparation, such as a simple garment finishing, to talk about meditation and other content, access to content should not be too long, to the words of blessing and encouragement for the theme. In the film interview,APPLE A1181 Battery the interviewer you can be farther away, and then the camera than in front of his chest, it is best not to use the general scene, took the microphone and handed him to shoot himself in order to avoid recording over the surrounding noise large, then shoot button.
