Photographic Film

Photographic film is a sheet of plastic (polyester, PET, nitrocellulose or cellulose acetate) coated with an emulsion containing light-sensitive silver halide salts (bonded by gelatin) with variable crystal sizes that determine the sensitivity, contrast and resolution of the film. When the emulsion is sufficiently exposed to light (or other forms of electromagnetic radiation such as X-rays), it forms a latent (invisible) image. Chemical processes can then be applied to the film to create a visible image, in a process called film developing.

Famous quotes containing the words film and/or photographic:

    All film directors, whether famous or obscure, regard themselves as misunderstood or underrated. Because of that, they all lie. They’re obliged to overstate their own importance.
    François Truffaut (1932–1984)

    ... the most grandiose result of the photographic enterprise is to give us the sense that we can hold the whole world in our heads—as an anthology of images.
    Susan Sontag (b. 1933)
