Abstract
A method to recover the resources incorporated in a photographic material is disclosed. An exposed silver salt light-sensitive photographic material is subjected to color development processing; the obtained image information is optically read; digital image information is obtained by converting the read information to electrical signals, and the resulting image information is recorded on a recording medium, and resources incorporated in a photographic material is recovered from the processed photographic material.
