A camera that exposes photographic film to light in order to take a picture. Used since the late 1800s, the film is a chemical emulsion on a plastic substrate that is sensitive to light. When exposed, an analogous image of the scene is created within the chemical layer of the material (see film). All film cameras are analog cameras (see analog).Film-based still cameras have been made for a variety of film types including 35mm, Advantix, 120, 220 and the larger 4x5 and 8x10 formats. Film movie cameras capture consecutive images (frames) on 8mm, 16mm and 35mm film. Contrast with digital camera. See cine.
