A photography system includes a plurality of film units and a remotely-accessed look-up table. The film units each have an access code that can be accessed independent of a filmstrip or digital image store. The look-up table has a read-write logical memory unit allocated to each of the film units. The logical memory units each have an access right secured by a respective access code. In a method, the access code is generated, the logical memory unit is allocated to the film unit, and the film unit is sold or otherwise transferred. The film unit is accompanied by the access code for that film unit.
