摄影技术3（Photography 3） Photography 3 Personally think that the focal length of a DC is about 28 135mm or so is enough, at the telephoto end, 200mm is the limit, not the pursuit of the zoom range is too large for DC, telephoto DC quality is generally not high, the wide-angle end has the best 28mm film are very scenic and Cultural Square Then, without 28mm, 35mm was barely enough. In the fuselage, be sure to buy a flip screen. This is one of the advantages of DC, so you can more easily view, especially when filming the flower. You can also make him or her unconscious of a strangers eyelids without being noticed. In the function aspect, must carefully look at the manufacturers explanation material. Its not important to have manual functions, there is the best, there is the same function is essential, that is, exposure compensation (use later). Look at macro functions, what is the focusing distance recently, distance as small as possible, such as 1cm, or even zero distance. Generally speaking, 5cm and 10cm are more common. Some DC also have anti shake function, this function is dispensable. DC shooting operations Using DC, in most cases, the P file is enough! If the camera has a jitter flag (different camera shake marks are different), use the tripod or flash. Several basic concepts are introduced first The shutter is the time the camera allows light to enter. The aperture is the size of the lens aperture. Be careful： The smaller the aperture is, the larger the aperture is, the larger the aperture; The larger the aperture, the smaller the aperture, or the small aperture. For example, the aperture values F2.8 and F8 contrast, F2.8 is the big aperture, and F8 is the small aperture. The shutter and aperture determine the amount of light that goes into the camera in unit time. If the amount is just right, then the photo is exposed correctly; if the amount is low, then the photo is not exposed; if the amount is too much, then the photo is overexposed. If you use the A file, th
