Photographic Processing

Photographic processing is the industrial process by which conventional photographic film is treated after photographic exposure in order to produce the desired negative or positive image.

Photographic processing does three things: it transforms the latent image into a visible image that can be seen, it makes the visible image permanent, and it renders the film insensitive to light.

The general process is similar whatever the make of film or paper. Although generally not considered "conventional," exceptions include instant films such as Polaroid and thermally developed films.

Kodachrome cannot be processed except in Kodak laboratories. There are also a small number of relatively uncommon processes using dye decomposition technologies such as Cibachrome.
