ABSTRACT:
An improved photographic copy apparatus, usable with an original photographic picture to be copied and a photosensitive image recording material having different normalized image area formats thereby requiring cropping of the projected image of the original, for previewing the original picture, selecting a desired portion thereof to be copied that is compatible with the format of the recording material on a normalized basis, and projecting an image of the selected portion onto the recording material for exposure. The apparatus includes a viewing station having a selecting frame thereat. A viewing station picture holder is mounted for movement over the frame, framing the selected portion. By means of a connector, the viewing picture holder is coupled to a projection picture holder that is automatically moved transversely with respect to the lens axis in response to the framing procedure to automatically set it to a corresponding projection position whereat the optical system will project the same selected portion after the picture is transferred from the viewing picture holder to the projection picture holder.
