Abstract

This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a dry thermal process without the use of aqueous solutions in which a blocked developing agent located within the photographic element is thermally activated or unblocked, optionally followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in a dry thermal process.
