What does the lens include?
Zoom lens, also known as slow motion, refers to a lens that changes the distance between the subject and the audience by changing the focal length inside the lens without changing the position of the camera and the subject, thus making the picture larger or smaller. Using the zoom lens, we can simulate the push-pull shooting mode and produce the illusion of moving.
Slow motion, also known as slow motion, refers to changing the running speed of the lens and shooting the subject at high speed, that is, the camera is at 48? 72% frame running speed (normal operation is 24 frames per second), which is 2, 3 and 4 times faster than normal shooting. When the screen is shown at 24 frames per second, the actors' movements will slow down, as if they were walking on clouds and getting high.
Snapshot means that when shooting, the running speed of the camera is slowed down, so that the picture taken per second is less than 24 frames (that is, the film passed by is not one and a half feet), and the picture changes quickly when showing. This kind of shooting, also known as degraded shooting, is generally used to create tension.
