Optical printer

A 35 mm optical printer with two projector heads, used in producing movie special effects. Starting from the left, light is shining from the lamp house, then at A is the first projector's film gate, at B a lens that projects the film in A onto the second projector's gate C. At D is the lens of the camera, the camera's finder is at E and the adjustable shutter control at F. The heavy base G contains all the electronics needed for controlling the printer.
Inexpensive J-K 16 mm optical printer using a Bolex camera.

An optical printer is a device consisting of one or more film projectors mechanically linked to a movie camera. It allows filmmakers to re-photograph one or more strips of film. The optical printer is used for making visual effects for motion pictures, or for copying and restoring film material.[1]

Common optical effects include fade outs and fade ins, dissolves, slow motion, fast motion, and matte work. More complicated work can involve dozens of elements, all combined into a single scene.
