What are the five requirements of photography? How to achieve these five requirements?

1. Plane In general, the TV advertising screen should be horizontal and cannot be tilted. When shooting subtitles, shots with horizons and buildings, the requirements for flatness are more stringent. But if you want to pursue differentiated visual effects, you can also shoot at an oblique angle. Some cameras have crossed lines on the ground glass of the viewfinder, which helps the photographer to keep the picture level when shooting. If you shoot with a tripod, you can correct the levelness of the camera according to the bubble level on the tripod. 2. Stability means keeping the picture stable and not shaking. When shooting with a telephoto lens, the photographer should hold his breath or rely on a stabilizer to stabilize the camera. You usually use a tripod. 3. Clarity means clarity, which means two aspects. First, the image of the main object must be clear; Second, the foreground and background images within a certain depth range must have sufficient clarity. For close-ups and close-ups, the picture only requires clear subject. For the middle panorama, in addition to the clarity of the main object, it also requires the clarity of the scenery before and after a certain range. 4. Uniformity This is the same requirement for all kinds of sports shooting, that is, the panning speed, zooming speed and moving speed of the lens are all required to be uniform. 5. In the shooting process, whether it is focusing, framing, exposure, shooting frequency, or shaking, moving, pushing and pulling the lens, it must be accurate.
