On five basic angles and functions that can be used in filming.

Answer: A bird's eye view may be the least important of all angles, because some of them are just taken directly from the sky. People sometimes feel that the scenery they take is abstract and difficult to identify. This angle is very expressive and is the view of Almighty God. The characters in the picture are like ants, very small. When shooting at high altitude, the lens is placed on the elevator or at a certain natural height, and the feeling of giving priority to the audience is not outstanding. Aerial photography only gives the audience a general impression and does not imply fate and prospects. The overhead lens is not suitable for expressing speed, but it is effective for expressing dullness. The importance of background and environment is prominent, and the scene will make people lose their luster. Bowing your head will reduce the importance of the theme and can be used to express the inferiority of the characters. Head-up lens can create the characters we want. Avoid using abnormal angles, and you can "avoid" subjective colors. The director treats all the roles in his films equally. Let the characters in the play show themselves in the development of the plot. The upward shot lens can increase the height and enhance the vertical sense of the picture. In practical application, he can make short actors look taller. The moving speed will be faster, which will make the violent scene more chaotic. The surrounding environment shrinks, and the sky or ceiling becomes the only background. Head-up lens can make the audience feel that the subject is tall psychologically, and gradually form a kind of pressure on the audience's psychology, resulting in insecurity and depression. The tilt angle is that the camera is deliberately not placed on the plane when shooting. The horizon in the image is tilted and the characters look unstable. This angle is often used to shoot subjective shots, such as injuries, drunkenness, dreams and so on. Tilting the lens makes the audience feel nervous and uneasy.
