What is translation? What's the difference between moving the lens? Function?

Jitter lens is a shooting technique in camera shooting. In addition to panning, there are also pushing, pulling and moving the lens.

When we observe static or moving objects, our heads and eyes will shake horizontally or vertically, and the "panning" when using the camera simulates our movement. Panning refers to changing the shooting mode of the camera optical lens axis with the help of the movable chassis on the tripod or the photographer himself as the fulcrum when the camera position is fixed. The "panning" we often hear refers to the pictures that are panned out.

When do you need to shake the camera? I think there are several common suitable scenarios: 1. When you can't include all the scenes you want to shoot in a still picture, such as shooting mountains, grasslands, deserts, oceans and other vast and far-reaching scenes, panning will play its unique expressive force. 2. Shooting moving objects, such as a group of children running on the beach, requires the photographer to shake the camera horizontally to show the lively and cheerful image of the children. 3. It is used to show the internal relations between two objects. If two objects or things are arranged in the starting frame and the left picture of the panning lens respectively, and the two points are connected by the panning lens, then the relationship between the two objects or things will be prompted or implied by the connection caused by the lens movement. Of course, there are some more professional panning skills, such as using the panning lens to express the subjective lens, or realizing the transition of the picture.
