ABSTRACT:
A device for adapting a process or copy camera so that it can be used to expose smaller film employs a cover member that is shaped and dimensioned for mounting on a conventional process or copy camera back to cover the frame opening over which a sheet of film is normally placed for exposure. A recessed portion in the cover member extends through the frame opening to define a secondary frame opening in a selected focal plane ahead of the camera back, and components are included for removably mounting the cover member on the camera back and for holding film over the secondary frame opening for exposure.
