Moving skills of plane lens

This lens technology was inspired by 1896, when French photographer Promio was on a yacht in Venice. He envisioned "shooting with a moving film camera, so that stationary objects can also move", so he pioneered the "side lens" in the film, that is, putting the camera on a moving car and shooting to one side of the track.

The purpose of this kind of lens is to show the spatial relationship between people and things, people and things in the scene, or to show something coherently. There are similarities between moving lens and shaking lens, both of which are to show the relationship between subject and companion in the scene, but the visual effect on the screen is completely different. Pan-tilt lens means that the position of the camera is fixed, and the shooting angle and the angle of the object are changing, which is suitable for shooting distant objects. However, the moving lens is different, that is, the shooting angle is unchanged, the camera itself moves, and the angle with the object is unchanged, which is suitable for shooting objects and subjects with close distance.

Mobile phone photography is mostly dynamic composition. When the subject presents a static effect, the camera moves to make the scene pass through the picture in turn, resulting in a visual effect of patrol or display; When the subject is dynamic, the camera moves with it, forming a visual effect of following. It can also create a specific mood and atmosphere.

When moving the lens, you can use other moving tools, such as airplanes in high-altitude photography, trains and cars in the wilderness, in addition to the moving car laid on the track. Its movement can be roughly divided into lateral movement and deep movement according to the direction of movement. When the camera is not moving, changing the focal length or moving the subject in the background can also achieve the effect of moving the lens.
