Abstract

A method provides archival storage of information related to a photographic film unit having a local data memory. In the method, a logical memory is allocated to the film unit. The logical memory unit is physically remote from the film unit. Photofinishing parameters for the film unit are written to the logical memory unit for use by a photofinishing unit. The photofinishing parameters are also written to the local data memory. After an expiration of time, the logical memory unit is no longer maintained. A replacement logical memory unit can be later reallocated to the film unit and the information in the local data memory can be written to the replacement logical memory unit.
