Does all photographic film and paper contain silver?

0

No. All unused photographic film and paper contains recoverable silver, as does processed black-and-white material. Exposed and processed color films and papers, however, contain only a dye image. In these cases, the silver has already been removed during processing and can be recovered instead from the appropriate processing solution. The amount of silver in the film or paper can vary considerably depending on the type of product, whether or not it has been processed, and on the density of any silver image.
