Description
Cine camera
This is a camera that takes motion pictures. It is similar in many ways to a normal still camera, with a light-tight compartment for the film, a lens, and a shutter. A cine camera takes a series of photographs in rapid sucession at a steady speed.

The film is moved one frame at a time past an opening through which the film is exposed. The motion is produced by a claw shaped device that slots into perforations on the edge of the film. The film is stationary for a short time as the claw engages further along the film, and this is when that frame is exposed.
