What is a push-pull swing?

This is a camera term. Refers to the six states in camera shooting. Push refers to the shooting technique of changing the shooting scene from a big scene to a small scene by moving the lens straight forward or rotating the lens. On the contrary, pulling refers to the shooting technique of changing the shooting scene from a small scene to a large scene by moving the camera straight back or rotating the lens when shooting from the front of the camera. Swing refers to the shooting technique of moving the camera from left to right or from right to left with the camera as the axis. Displacement refers to a shooting technique in which the camera direction is at right angles to the camera moving direction when the camera moving speed is relatively fixed. Follow-up refers to the technology that the camera follows the shooting when shooting a moving object in the same direction as the moving speed of the shooting object. Swing refers to the shooting technique of quickly shaking from a fixed scene to another scene with the camera as the axis.
