What's the use of photographic perspective?

Refers to the lens of distant things, and the characters only occupy a small position in the picture. Usually used to show the whole picture of the environment. Vision includes grand vision, which is often used to express the vast space environment, large-scale character activities and magnificent scenes. However, vision can also be used to express the emotions and meanings of characters. In the movie "Lin Zexu", in the scene where Lin Zexu rushes to the city wall and overlooks Deng Tingzhen's departure by boat, three different images are used in succession, which makes the picture full of parting and sadness. The use of vision can also keep the style of the film consistent. In the Japanese film The Call of the Distant Mountains, a fight is put in the perspective from a child's perspective, which keeps the unity of the film's quiet style. Close shot refers to a shot that captures the upper body activity of a character, or a shot that shoots a part of a scene equivalent to this. In close range, the environment has always been in a very secondary position. Close-up is often used to emphasize the expressions and important subtle movements of characters, or to show the parts of objects, which can vividly and strongly show the relationship between characters and their thoughts and feelings, so that the audience seems to be in the event of character activities. Close-up is one of the main scenes that focus the audience's attention on the characters, and it appears frequently in movies. Pushing the lens refers to the way that the camera lens pushes the camera from far to near when the position of the subject is still. This technique makes the visual field of the picture from far to near, the visual field from big to small, and the main part gradually fills the screen, gradually enhancing the visual experience of the audience. There is a difference between fast shooting and slow shooting. Slow push makes the audience pay attention gradually, while fast push can produce a sense of urgency. When shooting with zoom lens, switching from short focal length to long focal length can also produce various lens push effects. But there is still a difference between zoom push and lens push. Zoom push only changes the perspective of the lens, which leads to the change of the distance of the scene inside the picture, which is different from the perspective relationship and depth of field of the lens and the real feeling of people in motion. Pull lens refers to the way that the camera lens gradually shoots from near to far by fixing the position of the subject. When the viewing range changes from small to large, the viewpoint will move from front to back, and the picture will gradually move away from the subject or change from one object to more objects. There are also fast and slow shots, and zoom lenses are also available. There are many functions of pulling the lens, which can let the audience gradually understand the relationship between the part and the whole in the same lens; It can predict an ending in a certain image composition, and can also show artistic effects such as the mood and situation of the characters. Pan is also called "pan" or "shake" for short. Refers to the static position of the camera, the fuselage moves up and down, left and right, and rotates on the chassis on the tripod, just as we stand in the same place and look at people or things around us. The basic function of translation is to change the content of the picture without editing. Shake the camera from left to right, up and down, and then flash. Flash shake, also called lens shake, is a very fast panning lens. They all present vivid dynamic composition, different artistic performance effects and diverse expressive force, such as gradually showing a broad environment, slowly or quickly showing the mental outlook of dynamic characters, and setting off emotions and atmosphere. The use of translation is closely related to the audience's visual feelings and viewing emotions. The different translation speed will cause various changes in the audience's visual perception, and the speed at which the audience recognizes and accepts things in the picture also restricts the translation speed. Moving lens means "moving photography" and "moving photography", which is called "moving" for short. Broadly speaking, all sports photography methods are mobile phone photography. Mobile photography here refers to putting the camera on a tram or other means of transportation (trains, cars, planes, etc.). ) and shoot objects while moving in all directions along the horizontal plane. According to the direction of movement, it can be roughly divided into left-right movement, lateral movement and deep movement. When the subject is stationary, the camera moves to make the scene pass through the screen in turn; When the subject is dynamic, the camera moves with it, that is, it moves with it. The combination of panning and panning can form a panning shooting mode. The moving lens interweaves the moving people with the changing scenery, which can continuously show the vast space environment, show the activities of the characters with strong dynamics, reveal the psychology, render the atmosphere and form a powerful modeling impact.
