Answer:
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. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and resolution of the film.Photographic film is a sheet of plastic used to record pictures. The plastic has been specially treated, so it is sensitive to light. That way, it is possible to record an invisible image with the plastic when it is exposed to light. Normal film is shipped in small canisters (boxes) that protect it from the light.George Eastman
The use of photographic film was pioneered by George Eastman, who started manufacturing paper film in 1885 before switching to celluloid in 1888–1889. His first camera, which he called the "Kodak", was first offered for sale in 1888
