Q: I shoot digital photos often appear out of bright or dim side of the case, may I ask why there will be a digital camera metering errors happen? How to make?

A: The digital camera automatically metering is based on “standard dust” to determine, is the assumed rate is reflective metering region 18%, followed by determining the ratio of the metering aperture and shutter values, source of 18% of this value according to the natural landscape in the middle of the performance may be reflective tone, tone if the majority of white viewfinder screen, then if the camera automatically determine the aperture metering Shutter value to shoot, then get the photos taken will be an underexposed photo white background will appear gray hair looks so reflective rate of more than 18% shooting scene, the need to increase the HP pavilion dv7 battery replacement camera’s exposure compensation value, whereas if the reflection rate of less than 18% shooting scene, for example, black background, shoot Photos tend to have exposure, black background will become gray, so the reflection rate of less than 18% of the shooting scene, the need to reduce exposure. Simply means “white with black cut.”

Although digital images can be post-digital darkroom processing to adjust the exposure, but for an overexposed image, shadow detail and levels have all been lost, in order to adjust the back is difficult, but if it is less exposed serious photo, correction occurs after exposure more noise, the details will be lost, so try to get pictures taken with the correct exposure.

Q: The computer can only display JPEG files 24BIT full color, that is, a PANASONIC cga-s006 battery digital camera as long as the configuration 8BIT the A / D converter will be able to meet the need, but why use more than one converter 10BIT it?

A: The reasons are as follows: First, the high-end digital cameras usually use RAW format photographs, RAW when shooting can fully record all the raw data, get rid of the shackles of JPEG standard, to achieve the perfect color and quality performance. Second is to increase the combined calculation of the reference digital image data, some of the DSP digital camera with enhanced resolution for the IBM THINKPAD T40 battery program forces, this program mainly with reference to neighboring pixels of pixel sampling performance, do a statistical made. Thus, BIT the higher the A / D converter to sample with more parameters, relative to the combined 24BIT JPEG file out of the performance better.

Therefore, each digital camera red, green and blue more than the output to be at least 10BIT (1024 gray scale) for the job is currently configured 12Bit most of the A / D processor. Individual high-end products is reached 14BIT.

Q: I would like to ask sensitive SONY NP-FH100 Battery CCD ISO ability to improve the methods are there? Another CCD’s exposure latitude is much worse than the traditional film it?

A: Use a fixed CCD camera as a light-sensitive components can not be like a traditional film camera, to be replaced as selected higher or lower photographic capabilities. To increase the capacity of CCD ISO there are usually two ways, first, simplify the CCD from a particular region to improve the signal pixels on the ISO, because it can not be physically larger CCD sensitive area, through joint matrix to simulate the handling of large photosensitive area way, so the higher the ISO to be relatively lower resolution. Another way is through a specific signal enhancement circuit, according to data operations to obtain a reasonable performance of the exposure, but usually accompanied by noise generation. Therefore, the maximum ISO value of the HP Pavilion dv4 battery pack digital camera is mainly dependent on the maximum acceptable signal to noise ratio (S / N).

Under the accurate exposure, CCD better than traditional film to capture images of a wide tonal range. An ordinary CCD can record 250:1 (eight aperture) around the high-contrast scenes. High-end FF CCD system can handle nearly 1000:1 tonal range. However, the final output image on photo paper only reappear about 32:1, or 5 aperture range of hues.

Q: I’m going to buy a digital camera, mainly for landscape shooting, what is the market big 10X zoom product better? How to determine the reasonableness of the digital camera focus?

A: The telephoto digital camera does have many unique advantages, such as can be taken to far away objects, and can capture a close-up photo of the background to the virtual. But for shooting scenery, the wide-angle is the most commonly used. To record bits and pieces of daily life, wide-angle can be better qualified for the job. The telephoto cameras on the market today, and its wide-angle 38mm focal length is usually around, for the average home user and the users love landscape photography, this focal length and not too reasonable.

So from your demand, I suggest you choose a ACER Aspire 5735Z Battery digital camera with wide-angle lens. The camera should be at least 28mm wide-angle end of the following, now meet the requirements of the products on the market a lot, even to the end product of the wide-angle 24mm, very suitable for landscape photography.

Q: Will the number of ordinary digital camera Why is the focus more than it? Can even be free to choose the focus, and more What are the benefits of focus?

A: For SLR cameras, the more focus and focus on the selection means high prices. This is determined by the structure of SLR cameras, the focus is a separate component, in order to ensure high-speed AF, selectable Focus range and location are very limited. The common digital camera’s focus is to test the designated area on the CCD imaging, phase analysis done by AF, so in theory any of CCD position, of any size are able to separate out the regional analysis and focus, then 5 The above points focus on a few products, some products are even free to choose to focus. Such as the Canon 2002 years later, almost full range of products also have the ability AiAF, center of the Dell Latitude C600 Battery screen that can move freely on most of the focus areas.

Flexibility to pursue creative, photography veteran often dull and will not be subject to the composition placed in the center of the screen, to free choice of focus, innovative composition will bring great convenience, no matter what position the main body, can the focus will shift in the past, dedicated to the composition without the need to focus distraction.

Q: I am a digital photography enthusiasts, often for a long time to go out shooting, going to buy a “digital companion” to store photos, may I ask how to choose?

A: At present the market “Dell Inspiron 9400 ac adapter digital camera companion,” many types of products, most of the photos used only for storage, but some products have started to offer color LCD display and more features, and some products are not simply the sense of digital camera partner, and also can be used to listen to music, watching movies, playing games.

Simple “digital camera companion,” is bound to be a transitional product, I suggest you purchase multi-functional products, but such prices are usually more expensive, so you can consider buying second-hand pocket notebook. In fact the price of memory cards is now much reduced, two 1GB CF card or SD card prices, but some one thousand, you can store thousands of photos, fully able to meet the needs of ordinary ACER Aspire 3680 Battery film, “digital camera partner” role is not very big.

Shoot a lot of fuzzy, low resolution, exposure and composition bad photos of people never rare. Whether they have been the first time the idea of ​​pressing the shutter brainwashing, or just realize that the subject is not always stationary, in short, too many people forget the iPad 2 Foldable Leather Case camera is just a tool only – one to capture the life in a time of tools.

This article will list five digital camera users to avoid errors.

First, take low resolution photos

In order to squeeze out the last bit of HP Pavilion DV9000 Adapter memory card space, someone will take low-resolution photos. If your photo is only used to send e-mail or uploaded to the dating community, then no problem. But if you want to print out photos, albums and even trying to do how to do?

Taken to adhere to the highest resolution is much more reliable. You can no pressure to cut, print, zoom them, of course, can be compressed and then sent to the Internet. Now the SD memory card is not expensive, does not require much investment.

Second, once only a photograph

This may be from the film era “genetic” off the habit, because a roll of film is only 36. However, using a digital camera, you can always shoot satisfaction – but also a feature called Dell Inspiron 1501 battery Continuous. Compared to only take one time, this can greatly improve the success rate of the film. If the photo shoot, you have the opportunity to shoot one all eyes open, a smile is just right of the photo.

Third, can not delete photos

We almost have this idea: “to keep it all these pictures, maybe one day I would use.” Indeed, unless this is a special event or person only a Dell Inspiron 1501 battery picture, or does not exist such a situation. Boldly delete those fuzzy, out of focus, composition and exposure of bad pictures. Cold, and these “garbage” accumulation of speed than you can imagine.

Related to this is a mistake not to make judgments on the pictures into the computer. In a small camera that has a low-resolution screen is difficult to really judge the picture quality. Therefore, you must promptly put them into the computer, and delete those “bad” photo.

Fourth, practice using the camera does not spare

Aha, dell inspiron 1545 battery automatic settings. Why do people feel able to shoot automatically set the best photo? In most cases, automatically set to be the only one “OK” photos. You should carefully read the instructions in the e-learning (such as new photography photography class), and spare no practice. You need their own research in an environment, how to get the best results.

Fifth, poor composition

Maybe your grandmother’s floral sofa and works of art hanging on the wall no way, but in the Sony VGP-BPS13 battery portraits and other photos when you can take the initiative to complete the composition. Some people close to sit down and change the focus, change lighting, etc., these approaches can shoot different pictures.

That’s where you should correct the error as soon as possible. First, the camera is set to high resolution and continuous shooting. Then buy a high-capacity memory card. Then delete those pictures should not keep, and try to practice using the camera – anytime, anywhere. Finally, in thinking about how to shoot before shooting again. Before pressing the shutter may wish to pause, I believe that soon you will enter a new Dell Inspiron 1545 battery realm.

First page: The flash does not light

This problem often occurs during filming, but you may wish to check the status of the sony vgp-bps9 battery machine itself, may have the following conclusions.

1, flash is not set. Users can press the flash pop-up bar, set the flash.
2, the flash is charging. You may wish to wait until the orange light stops flashing.
3, photo objects bright. At this point you can use the secondary flash mode.
4, in the case of the flash is set, the indicator light on the control panel, indicating the work exceptions flash. Please repair.

The second page: The camera automatically turns off

1, if the HP Pavilion dv7 battery digital camera suddenly shut down automatically, you should first think of is the battery is low. Is a power-hungry digital cameras, battery power is low because the phenomenon often closed, and if so, you must replace the battery.

2, if after replacing the batteries, digital camera, or could not be opened, and you find the camera is hot, that is because the continuous use of the camera for too long, cause the camera to overheat and automatically shut down. Stop using, so it is cool before use.

Third page: Press the shutter release button can not take pictures

1, just taking pictures of the photo is being written to SmartMedia card, this time may wish to release the shutter release button, wait until the green light stops blinking, and then use the MOTOROLA NTN7143 battery LCD screen display disappears.

2, SmartMedia card is full. SmartMedia cards should be replaced at this time, you can not erase all the photos the photos or send data to a personal computer and erase.

3, is to take pictures or write SmartMedia card, the battery is depleted. The battery can be updated and re-photographed.

4, the camera thing is not in the scope or camera to work effectively together is difficult to automatically lock. Users can refer to the standard mode and macro mode of the effective working range, or reference to auto-focus part.

Fourth page: Camera memory card not recognized

1, using incompatible with the sony vgp-bsp13/s Battery digital camera memory card. Digital cameras use different memory card is not the same, and most digital cameras can not use more than one memory card. Solution is to put your digital camera can use the memory card.

2, memory card chip damage. Then replace the memory card manufacturers have to look for.

3, memory card image file is destroyed. This phenomenon is due to a memory card in the filming process is removed, or due to a serious shortage of electricity caused by the sudden closure of a digital camera. If you re-insert the memory card or reconnect power, the problem still exists, you must format your memory card.

Fifth Page: Hp pavilion dv6000 battery camera connected to a computer to send data to a computer error message appears when

1, the computer is undocked good. Users should immediately correct plug cable.
2, the power is not turned on. Power press the power button.
3, the battery runs out. Must update the battery or AC power adapter.
4, the inappropriate choice of serial port. Confirm the operating system software to use the serial port is selected properly.
5, no serial port available. Instructions for use of personal computers can empty out a serial port (only for Macintosh Switch Talk / LocalTalk function).
6, the inappropriate choice of image transmission speed. To choose the right computer, transfer speed.
7, is not installed TWAIN / Plug-In. Can be TWAIN / Plug-In installed on your computer. When the Press any key to are not doing anything, press card cover reset button, then press the power button to boot.

Sixth page: HP 361909-001 battery LCD display when the image was defective or a black screen

LCD after power can show the current status and function of the normal setting, but can not display images correctly, the screen obviously defective, or a blank screen. This happens, most of CCD image sensors due to defective or damaged. You should replace the CCD image sensor. This situation occurred in the second-hand digital cameras, buy used digital camera, be sure to carefully distinguish CCD image sensor. If the camera does not have LCD screen, CCD imaging devices can not directly determine the general good or bad, but sometimes damage the CCD when shooting all normal, until the computer to download photos dark photos only to find, therefore, can only see through the real output of batteries shop photo shoot quality.

Currently, most digital cameras usually have the flash to aid in shooting. Generally have the following flash modes, namely, automatic flash, red-eye reduction on and off the flash (Auto / Red-Eye Reduction / Off). High point of the product and then provides “Flash (fill in or ON)”, even “slow flash (SLOW)” function.

Auto Flash: Usually traditional film Sony VGP-BPS8 Battery cameras and digital camera without any configuration changes when the flash mode are preset in the “Auto Flash” mode. At this point, the camera automatically determine the shooting scene light is sufficient. If insufficient, it will automatically open the flash when shooting flash to make up light. Most of our shooting situations, the “Auto Flash” mode is enough to cope.

Forced Flash: whether in bright or low light environment, both the flash to flash. Often used in light of the figures on his back to shoot, can enhance the brightness of the characters, but likely to cause excessive noise and exposure increases.

Turn off the flash (forced flash is not): forced flash off camera. No matter how the shooting environment lighting conditions, were not allowed to flash. This feature is best suited to place prohibiting the use of flash photography.

Red-eye: called the Redeye reduction, in the SONY NP-FR1 Battery digital camera is generally a sign of “eyes.” “Red Eye” phenomenon in shooting portraits (especially the relatively close distance, than the dark environment) often occur. This is because the retina of the eye caused by flash reflection. If you do not want to shoot out the eyes of people or animals, a “red eye”, you can use a digital camera’s “red-eye reduction” mode to let the flash will flash once or several times, make the pupil to adapt to, and then to the main flash and the shooting. The following was running red-eye reduction, and open red-eye reduction mode, beat out two different pictures.

Slow Sync: whether in bright or low light environment, both the flash for flash. Usually the characters on his back light to shoot, can enhance the brightness of the characters, but likely to cause excessive noise and exposure increases. In low light conditions when taking pictures, plus if you use the flash to shoot a high shutter speed can easily lead to the foreground subject is too bright, even dazzling piece of white, while the background is still dark, can not tell the details. The “slow flash sync” will delay the release of a digital camera shutter speed to flash lighting future, with a slow shutter speed (such as 1 / 5 seconds) for camcorder batteries low light background exposure. In this way, we can capture both the foreground and background are harmonious exposure photograph.

Front / Rear-Curtain Sync: In low light situations, the shutter speed is slow, and front / rear-curtain sync flash, basically does not increase the shutter speed. Such as the normal metering, when the maximum aperture, shutter speed is 1 second. Front-curtain sync flash, the flash while the shutter open 1 / 90 seconds, and then continue the exposure of 1 second or 1 / 2 seconds. Rear-curtain sync and reverse sync before the curtain, the shutter opens, the shutter closed until the last, began to flash.

Intelligent Flash: It is characterized according to actual needs, appropriate and reasonable to adjust the output volume. The camera’s sensitivity according to shooting, aperture and speed settings, and then select the scene mode according to the user to determine the accurate exposure. Thanks to the basic conditions for high sensitivity, the camera’s flash output at low exposure is accurate, so that you can completely avoid the “bleaching” or the status of the background missing.

Professional digital camera batteries from UK/US:

Canon nb-8l Battery , SONY np-fc11 battery , CASIO np-20 battery

We all know that generally the camera to focus before shooting, in theory, only be accurately focus photo of the part (focus) clear, the focus of the scene before and after the focus will be outside because of the focus and appears blurry. However, based on the lens, shooting distance and other factors, in focus before and after there will still be some distance from the scene can be clearly displayed and prevented from falling into the gray area, the scope of this definition will be called the depth of field.

The so-called depth of field, that is, shooting the Dell XPS M1530 battery scene, showing a clear scope of your subject. Depth of field may be very long, it may be very short, very shallow, we can adjust according to demand mode to control depth of field photography length.

Depth of field will affect the length of the general reasons, there are the following three:

1. The larger the aperture, the more shallow depth of field, the smaller the aperture, the longer the depth of field

In the same shooting distance shooting situations, the use of large aperture to shoot, because of shallow depth of field, the NIKON EN-EL14 battery subject before and after the scene will become more blurred. The use of small aperture, subject distance will be around the scene longer clear.

2. Lens focal length, the more shallow depth of field, the shorter focal length lens, the longer the depth of field

In the aperture, shutter speed are constant, shooting the same scene, shallow depth of field will make use of long lens. The use of wide-angle lens, the depth of field will be longer.

3. From the body of the more recent film, the more shallow depth of field, the farther away from the body when taken, the longer the depth of field

In the aperture, shutter speed, Dell inspiron 1525 Battery lens focal length is unchanged, shooting the same scene, when away from the subject closer, the more shallow depth of field. Farther away from the subject, the depth of field will be longer.

We can see from the above three points the length of the depth of field, mainly by the aperture, lens focal length and shooting distance to control, and therefore the need to control depth of field shooting situations, we can adjust these elements to the right of the photo shoot.

Ring in the early scenes have a depth of field above the lookup tables, can be read from above the range of depth and length, but now largely discarded auto focus lens of this design, or the lens is attached to a very simple depth of field sony np-ft1 battery table, practical function is not.

For the amateur photographer, it might read the depth of field tables are actually quite small, most people use rules of thumb to judge the depth of field length; Another method is to use the camera’s “depth of field preview” function, pressing the depth of field preview as the button is pressed, the length from the viewing window to determine the depth of field, which is the fastest and most direct method. However, its drawback is that when using a small aperture when shooting into the light because of the small quantitative change, and so depth of field preview button after pressing, looking out from the viewfinder will become darker.

In general shooting situations, the landscape of the occasions in the film, we often use a long depth of field to show the clear scene, so the way to use the shrinking aperture shooting. But because the CANON eos-300d Battery reduced amount of light into the aperture also followed smaller, so the shutter speed to low, you need to use the tripod to stabilize the body, which is often used in landscape photography tripod one of the reasons.

When we shoot portraits, the way will make use of shallow depth of field to blur the subject before and after the scene in order to highlight the themes of strength, the same shooting style can also be used in other occasions. To highlight the theme, shallow depth of field is a very convenient way, it is generally in the purchase of equipment, it will need to buy based on twelve large aperture Dell Inspiron 1520 battery lens, in addition to shooting in low light, the flexibility in the use of shallow depth of field is also an important reasons.
