ABSTRACT:
It is desirable to position instant film at the viewing imaging plane of a camera-processor having a light shield surrounding the viewing plane. The use of a conventional film holder causes interference between the dark slide and the light shield. By modifying the dark slide, the slide is completely removed from the film holder positioned within the special camera back, and the back is thereafter pivoted to enable the film to be positioned at the viewing plane.
