Austrian seconds photography is that it contains many elements, you can look at it as an art, but also a science, with the camera to create a certain extent, created with the same artist paint brush, but the emphasis on photography equipment but it The photographer must understand the characteristics of the camera and lens. However, because of photography so profound, involving the addition of elements, many people will have a lot of the misconceptions and delusions, there are a lot more friendly to novice photographers were unknowingly misled. Therefore, we specially concocted this article to share with you some of the photography is often misunderstood problem.
Myth 1: The higher contrast lens, higher resolution
Some friends shot, when shooting with a NIKON EN-EL10 Battery lens, you will find images taken from a high contrast (more commonly known as “hard”), or look sharp, they blurted out that a certain lens solution like the class. Once the photo to see a weak contrast (that is often referred to as more flexible time), it sounded Road lens resolution for bad. This way, it seems somewhat arbitrary, in fact, resolution and contrast are two things to, and should not be generalized, of course, and some related areas. What is the resolution? Resolution
(Resolution) is obtained through some standard tests to the data lines is to use a black and white chart with a different aperture shots, but the most standard data should be read by machine, but some magazines or Zuoren film imaging test used to determine the eye, it seems to be with some objective factors, such as the film’s treatment process or restrictions on the human eye, but generally acceptable, because at least be able to find a lens with different cases ( different aperture or focal length) of the resolution for performance, not compared with other lenses will do. In general, the more out in the same range of more lines of resolution for the number of the more force that is more sharp lens. What is contrast? Contrast (Contrast) although the resolution does not mean, but not unrelated, but can not say that the high contrast, high resolution for it. Contrast between the dark lens will actually refers to the ability of bit-level expression, an image must be both bright and dark contrast, high contrast between light and dark is clearly separated, while the middle may not be much gradient (gradation); and contrast low between light and dark is not that clear or not clear, but there are more levels, it seems likely to make people feel more rigid. For color or black and white images, the definition of contrast is the same. Most people misunderstand the high contrast is good, yes, indeed a more distinctive high contrast and tone light, but not rich in depth, they just lose their meaning high resolution, so that will hinder the overall performance carefully. However, contrast is indeed a very subjective thing, may not have a standard, but the specific PANASONIC cga-du14 battery lens on a full point would be more popular, not to mention today’s film also has very good contrast and levels, there are different options, such as for portraits designed, but also for accurate color designed to restore the film, film is also not too blind pursuit of faithful.
Myth 2: Canada is better than UV filter Skylight 1B
When buying a new lens, will consider buying a protective lens filters, and UV both general 1B SKYLIGHT, the former than the latter expensive, some say UV is just a piece of glass, and some pretty 1B portraits will be taken or if the color will more accurately, it will be partial election 1B, but this claim seems not appropriate. 1B skylight filter is the official color of a colored filter, is one of a standardized color correction filter, 360nm or less can trap light waves (of the more blue light to UV), and at the same time slightly The light absorption of about 550nm (ie green light), all in all are used to reduce the mountains or the beach shooting the phenomenon and bluish green leaves, reflection, portrait photography in the lush grass may need it. However, shooting in direct sunlight, this is a full-1B filter strips, in other words, it is only a piece of glass. UV filter is used to trap ultraviolet light invisible to the naked eye, so the color (usually color film milk film can not appear on the UV color) is no effect, but according to the manufacturer’s recommendations, its greatest effect infinity is taken to improve the fuzzy situation, but honestly, the weather is the ultimate deciding factor, if more than dust in the air or high humidity, increase the number of blocks UV is also a natural migration. If so, what is it best to add the filter is not it? Right, CANON NB-5L Battery optical is definitely good, because with a piece of glass, may be counter-productive, but this may not be detected by the naked eye, and then carefully weighed under the protection of the former group to buy a glass lens, it seems The optical loss than a little bit more important. But 1B or UV, it will be noted with respect. But the money to buy a piece of a multi-layer coating of UV was sufficient, and can protect the lens, but also reduce the optical loss, the more worthwhile.
Myth 3: professional film amateur film Liang Guo
Some friends often take a wrong impression that the image quality of professional film amateur film must be better than good, but often find that the facts are not so obvious to blame the camera used, lens, light meter, and so is not good enough, or even themselves, This seems a bit pathetic. Professional film does better than the local amateur film, amateur film, but certainly does not mean that badly, in fact, we just want to tells professional film is designed for professional photographers, they should be used well, solution is simple, learn How to become a professional photographer will be the line, not necessarily need specialized equipment, but is a skill, especially in dealing with film techniques. You may wish to try to buy some professional slides to try, you will find a place there will be a display refrigerator, and then carefully the instructions on the film, in addition to using the deadline, there is a proposed storage temperature, usually about twelve, three degrees. Professional film pretty fresh in enough, if we can save the environment proposed by foot, film will get the desired effect, but dispose of film, and at another to a shop, finishing shop and at another to B, there is no guarantee that each the performance of different colors strange miles. Of course, there are a lot of film processing methods, such as exposure factors, reciprocal rates, or may refer to the instructions manual. Amateur film is different, in addition to expire date, but also no other instructions, while generally more stable longer shelf life and high tolerance for general users, it seems more reliable.
Myth 4: X sync flash shutter shooting must use
Many Chinese and foreign photography books have mentioned X sync shutter this thing, even the fastest flash sync shutter of the term. But there are many misconceptions that beginners photography friends hard to use flash when shooting a shutter. In fact, the so-called flash sync shutter or the fastest flash sync shutter is generally refers to the shutter can be used for flash shooting, the fastest mean speed in that Kuaimen 以上 flash sync shutter can not be, otherwise it will take less than a full-clear images Gefei Lin This problem is present in the mirror after the shutter of the camera, each camera has its own design, the maximum shutter sync is not all the same. When using the MOTOROLA GP340 battery flash sync shutter speeds as long as any one of the highest profile, can be taken to effect a flash photo, but the slower the shutter, field of light and have a longer exposure time. For example when shooting indoors, if the maximum flash sync shutter shot, the background may not have sufficient exposure, which makes the main prospect of white light, and then view the dark dark; If a slow shutter (and even then the so-called Slow Sync photo machine or Night Portrait mode etc.) synchronized flash photography will be able to get more pictures of the atmosphere. In addition, when using slow shutter, or even before or after the optional curtain sync flash, you will open the door quickly adjustable flash, but also the flash before the shutter closes, can be taken to create special effects.
Misconceptions 5: Macro lens for close-up only
Macro lens is designed to shoot very close and set up, but some people say there will be shooting in the normal decline in the quality or superstition can only be used in photographing or macro shooting purposes. In fact, according to some optical test, whether in 1:1 or 1:2 and 1:50 ratio of shooting, the Macro lens aperture resolution for the most part have very excellent performance; and 1:49 or 1 : 50 time of testing, the same resolution than other non-macro lens focal length is much higher. But the biggest problem is macro-focus lens design is designed for short-range, so tens of centimeters to infinity in the distance may only need to turn the focus ring less than 45o, the accuracy may be compromised, but now The AF lens is very accurate, or can make up for this problem. Therefore, the distance to the normal macro lens shooting the scene, even people like no problem, f/2.5 or f/2.8 aperture may not be fully utilized, because a loss would be the four corners of light, and this is inevitable, but the charge was Iris has been able to solve the level, on the contrary, when shooting macro, small aperture likely to cause diffraction and, therefore, f / 8 to f/11 are more appropriate. However, some macro lens users will know, a very high resolution for CANON NB-2L Battery macro lens, photographs of them are listed as if a bit “hard bouncing”, but each have their own preferences, select a number, as you are right!
Misconception 6: incident light meter than the reflection-type quasi-
This statement is not comprehensive, objectively, in fact they are the same accurate, but only one type of metering means for people who believe that a more reliable one is understandable, since both have their own mode of operation and measurement methods. But the reflective light meter is to type a little trouble over the incident, since it is often to consider the limit of 18% gray, and incident type can be cast directly measure the brightness in the main, direct access to the aperture value. However, we are on the camera built-in reflective light meter, the advantage is easy enough to win in, because do not often walk in front of the main measure, but mostly TTL (Throagh the lens), lens of the loss of light, filters, etc. Exposure factors are also directly included to minimize errors, easy and reliable than the incident type. But the main subject and background color (eg black or white) will cause measurement errors, the only way is for exposure compensation, as long as we practice, to get the correct exposure is not so difficult. The incident-in itself has been better than a place of reflection, but is more cumbersome to use, if not mind more with a light meter, which is no problem, but do bear in mind that the filter before the lens into account factors such as . Also, if NikonF5 already have 3D RGB reflective light meter, which means that there can be reflective metering cabinet box out of place, as long as 18% gray to solve constraints, there is no doubt its accuracy
Myth 7: The most reliable moisture seal
During the wet season, making friends on the most sorrowful mood, because any moisture beloved equipment reimbursement, some people buy all kinds of crazy moisture supplies, such as dehumidifiers, dehumidifiers and so on. When it rains, would rather hide the camera lens into humidity allergic mad, like this, the summer may also shoot film with a tube could not finish, can be said to be very sad. Frankly speaking, the climate here in Hong Kong, to be lower than 60% RH day is far from adequate, let alone in the rainy season. However, all the equipment off and may not be completely moisture-proof, many people will have experience on the sealed box of “vintage” lenses will not know what solution had mold. In fact, to prevent the lens mold, anti-bacteria should not wet. To stop the lens mold, the first is to understand why mold, moisture and darkness are all beloved of mold, however, scattered bacteria in the air, there is very hard to detect, if sealed Cabinets, the same as the mold, if the added moisture beads ( usually with silica gel), can have some dehumidifying effect (but not permanent, will effect a total loss when the saturation), the market there can be sucked into the water moisture inside the device, although the water was effective, But I suggest that you be careful, be diligent that check whether full or leaking, but also to avoid excessive heat on the batteries shop place, because the transpiration of water as it may be. Therefore, many people prefer to have time to take the lens out of play or use, pleasure of seeing light has the opportunity to significantly reduce the mold. General on the air-conditioned room, as long as air circulation, coupled with low humidity, the opportunity to mold the lens is very low. If that equipment should hide for a long time, preferably in low humidity environment, the right amount of moisture into the material in a sealed box containing, remember to clean the lens in order to avoid bacterial growth. Some Electronic moisture control is also said to have a certain role, but the price is very expensive.
Misunderstanding 8: Always wipe lenses
The market for many devices and even wipe the lens clean lens solution, whether the lens should not often need to wipe it? Friends of the general nature is love making their own equipment, see the mirror on the dust had soiled her panic rush to buy something to clean the lens. Some people will use a sweep of the pump or to sweep away the dust blown off, and even wipe clean the lens paper and syrup, but it is not too good, unless the mirror on the stick is more difficult stains such as fingerprints clean, otherwise Do not wipe the lens surface with something hasty because it might get to spend the mirror may also be made part of the coating off, but now the film has been quite solid, but this has always been too dangerous. Recommended installation of a UV lens filter for protection or IB skylight, even if soiled wipe can also be free, even for a new, get to spend than how the lens of the camera more than considered. If it is really necessary to buy the lens or lens cleaning paper to be careful to avoid the use of alcohol, detergent ingredients, such as this lens will be damage, do not use detergent when the drops on the mirror, if the flow into the lens or on the edge of the lens, the lens will be damaged. Therefore, the best way is to try to avoid fouling of both ends of the mirror, if the dip application of pump gently blow away dust, HP Compaq 6910p adapter fingerprints or if soiled with grease available high-density fabric or leather polished wiped. If the house had mold or condensation (such as access to air-conditioned places), the best return on behalf of the original maintenance treatment center.
Misunderstanding of 9:50 mm focal length equivalent to the human eye
People often say that the standard 50mm focal length lens, also known as the human eye’s visual effects are similar, often said that images taken with a 50mm to the most honest and realistic. However, if carefully looked out from the viewfinder, as compared with the naked eye, the image size may have seen are not so, you will find 50mm lens, the image will be received by the brain is more than promising. If Perspective (Angle of View), 50mm lens is only 46o, but the human eye can be nearly 120o, but why has the human eye to see what the total is not enough wide 50mm lens? The problem is in the image plane size and the lens and the lens of the eye, respectively. Where the human eye is sensitive in the retina (Retina), while the places where light-sensitive cells is also limited to the point that yellow spot (yellow spot), the color of the cone cell induction (cone cells) than in black and white vision of the bar cells (Rod cells) less and more concentrated. Ever since, you will find to see things (such as reading), when seen only in the central part of learning, while other words outside the circle may not be able to see, but the film is different, as long as the camera angle coverage, while the principal is flat so, the plane will be clear, because the HP Pavilion dv9600 adapter film surface (24X35mm) are equally sensitive drugs. On the other hand, came out with a 50mm film image, the proportion with no difference in kind, as long as the image enlarged to the same size as the original place with the kind eyes, and you look at the real fact is the same as before, but this is not only a 50mm lens do, 80mm, 100mm, 180mm … … can do it. Is 50mm really where? Perhaps watching from the viewfinder close to the human eye can see, but it depends on the distance from the main body, remember: the human eye to see a 1:1 Life size, however, to see from the viewfinder is reduced small effect. There, 50mm lens or a clear focus is the human eye plane distribution are different, therefore, that the human eye close to 50mm and that seems to be little, but said no serious deformation of 50mm lens and viewfinder is a moderate range of “true” performance is or can.
Misconception 10: lens focal length will affect the perspective
Some friends used to say such and such a 20mm film camera is useful sense of perspective, and if so and so 300mm lens is very oppressive, that these all have different focal lengths for different sense of perspective. In fact, the perspective is not related with the focal length, while the perspective is the contraction of light effects, such as shooting from the ground with a wide-angle lens the whole building, the building up both sides of the line will shrink, not parallel. In general, there are three main factors that affect the perspective: the same distance. If kept in the same position, same angle, with the main point remains the same, but shooting the same subject at different focal lengths, the pictures are to have different The field of view (Field of View), while the principal will have a different magnification, with the longer focal length will be larger magnification; However, the perspective is a little too constant, do not believe can be multiple different focal length zoom in or out photographs to the same magnification of view, the ratio of the subject and the background is very similar, that is also similar perspective. Distance between camera and subject to change perspective and lens focal length has nothing to do, but with the same lens with a focal length, if different from the subject and the camera shot, there will be a different perspective effect. Or, how were different focal lengths when shooting the same subject, in order to shoot close to the main body of the same size, they change the shooting distance, the result will be taken to the 20mm of additional background, while the 100mm will be close to the effect of human vision and 200mm and may be photographed with the main background of “compression” or close to the photo. Another camera angle with the main impact of the perspective of the factors is the camera angle when shooting, if wide-angle lens when shooting low-angle shot from the standing of the portrait, the look will be a short upper body, lower body length, and from the high angle shooting, will have the opposite effect. If the level toward the main shoot, the deformation of this perspective will not appear. That we will or will not issue the above misconceptions about the photography, but Sony VGP-BPS5 battery photography has always been a very great variety of stuff, there are many issues which are worthy of discussion, future opportunities, or will again share with readers.
