Manufacture of
light-sensitive film
The discovery of the effect of light on silver nitrate has had a significant impact on the development of the image-makers - and the development of the photographic industry.
Photographic film is a strip or sheet of transparent plastic 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.
