Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals, for the purpose of taking photographs. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film.
