Ask professional photographers how to shoot good outdoor beauty. What are the taboos of outdoor photography?

What are the misunderstandings in photography? From: photographer Li Peng Bai Hui. Com expert Hall /4XFMLW shares some photography problems that are often misunderstood. Myth 1: The higher the contrast of the lens, the higher the resolution. Some photographers will find that their images taken with a certain lens have high contrast (generally called "hard") or look sharp, so they blurt out that the resolution of a certain lens is first-class. Once you look at a photo with weak contrast (which is often said to be soft), the image resolution of the channel lens will be very poor. This statement seems a bit arbitrary. In fact, resolution and contrast are two different things and should not be generalized. Of course, there are also some related places. Myth 2: adding 1B sky lens is better than UV filter. Whenever we buy a new lens, we will consider buying a filter to protect the lens. Generally 1B skylight and UV, the former is more expensive than the latter. Some people say that UV is just a piece of glass, but 1B will make people look more beautiful or have more accurate colors, so we will choose 1B, but this seems to be the case. Myth 3: Professional films are better than amateur films. Some photographers often have the illusion that the quality of professional film must be better than amateur film, but they often find that the fact is not so obvious, so they attribute it to the camera, lens, exposure meter and so on, or even themselves. This seems a little pathetic. Myth 4: Flash shooting must use X-sync shutter. Many Chinese and foreign photography books have also mentioned the X-sync shutter, and even the term the fastest flash synchronous shutter. However, many friends who are beginners in photography have misunderstood that a shutter should be used rigidly when flashing. In fact, the so-called flash synchronous shutter or the fastest flash synchronous shutter generally refers to the shutter that can be used for flash shooting. The fastest shutter means that the shutter speed higher than that shutter speed cannot be used for flash synchronization, otherwise a clear full-film image cannot be taken. This problem exists in cameras with shutters behind the mirror. Each camera has an independent design, so the highest synchronous shutter is not the same. Myth 5: Macro lens can only take close-ups? Macro lens is specially designed for very close shooting, but some people say that normal shooting will deteriorate or superstition can only be used for remake or macro shooting. In fact, according to some optical tests, the resolution of the macro lens is excellent in most apertures, whether shooting at the ratio of 1: 1: 2 and 1:50. When tested at 1:49 or 1:50, the resolution is much higher than other non-macro lenses with the same focal length. Myth 6: The statement that the incident exposure meter is more accurate than the reflective one is not comprehensive enough. Objectively speaking, both are equally accurate, but for those who only use a single measurement method, it is understandable to believe that one is more reliable, because both have their own operation methods and measurement methods. For example, NikonF5 has a reflective exposure meter with 3D RGB, which means there is room for reflective metering to jump out of the cabinet frame. As long as the limit of 18% gray scale is solved, its accuracy is beyond doubt. Myth 7: Sealing is the most reliable against moisture. In the rainy season, the photographer's mood is the most sad, because his beloved equipment is reimbursed at any time, and some people buy all kinds of moisture-proof products, such as dehumidifiers and dehumidifiers. Once it rains, I'd rather hide the camera lens and become a humidity allergy freak. So I may not be able to make a film all summer, which can be said to be very sad. To be honest, the climate here in Hong Kong rarely waits until the RH is below 60%, let alone the rainy season. Myth 8: Always wipe the lens. There are many instruments and even lens wiping on the market. Do lenses need to be polished frequently? The average photographer loves his own equipment by nature. When they see a little dust on the mirror, they feel scared and are eager to buy something to clean the lens. Some people will use the air pump to sweep away or blow away dust particles, or even wipe them with lens paper and medicine, but this is not good. Unless the stains on the mirror surface, such as fingerprints, are difficult to clean, don't wipe the lens surface rashly, because this may stain the mirror surface or part of the coating may fall off, but the coating is quite stable now, but it is still too dangerous. Myth 9: The focal length of 50 mm is equal to the human eye. People often say that the focal length of 50mm is a standard mirror, which is also called the visual effect similar to the human eye. It is often said that the image taken with 50mm is the most real and lifelike. However, if you look at the viewer carefully, the size of the image you may see is not the same as that of the naked eye, and you will find that the image under the 50mm lens will be wider than that received by the brain. Myth 10: The focal length of the lens will affect the viewing angle. Some photographers often say that a 20mm lens has a sense of perspective and a 300mm lens has a sense of depression, saying that these are all because of different focal lengths and different perspectives. In fact, perspective has nothing to do with focal length, and perspective refers to the contraction effect of light. For example, when shooting the whole building from the ground with a wide-angle lens, the lines on both sides of the building will shrink upward instead of parallel.
