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.
Claims8
A method to recover resources incorporated in a photographic material which comprises:
- processing an exposed silver salt light-sensitive photographic material by color development processing including a dye image-forming process but not removal of light-sensitive compositions and photographically processed material to form an image;
- reading the obtained image information by optical reading means;
- obtaining digital image information by converting the optically read information to electrical signals;
- recording the digital image information on a recording medium;
- and
- recovering resources comprising silver and film base from processed photographic material.
A method to recover resources incorporated in a photographic material, which comprises:
- processing an exposed silver halide light-sensitive photographic material by color development processing, without processing bleaching or fixing;
- reading the obtained image information by optical reading means;
- obtaining digital image information by converting the optically read information to electrical signals,
- recording the digital image information on a recording medium, and
- recovering resources comprising silver and film base from processed photographic material.
