Abstract
Photographic apparatus, such as a film recorder, uses the scanning mechanism provided for imaging photographic film to read the DX bar code on the film cassette. The DX bar code indicates the film type, film speed, and roll length. The bar code information is used to automatically set one or more parameters necessary for the proper exposure of the film.
