Light on Film

Effect of more light (read: longer exposure) on film

Photographic film is a sheet of plastic which is coated with an emulsion containing light-sensitive silver halide salts with variable crystal sizes that determine the sensitivity and resolution of the film. When the emulsion (in this film) is subjected to sufficient exposure to light it forms an invisible image.
