Abstract: A photographic display for depicting a three dimensional visual image including a supporting frame for displaying a photographic image including a height, width and a predetermined thickness. A viewing screen is provided and disposed to extend substantially along the height and width of said supporting frame and being positioned on a first side thereof. The viewing screen includes a plurality of substantially parallel lines having a predetermined width and being separated by clear spaces. A photographic image is provided and disposed to extend substantially along the height and width of said supporting frame and being positioned on a second side thereof, spaced from said first side by said predetermined thickness of the supporting frame.

Abstract: A photographic camera for three-dimensional photography has a housing which includes an opening to the interior on a forward side thereof and an aperture moveable transversely across the opening for selectively admitting light rays through the opening. Within the housing are located optical means for focusing the light rays along an optical path to a location adjacent the rearward side of the housing. At the rearward side of the housing there is located mechanical means for moving a planar object synchronously and in the same direction with the aperture. The improvement comprises an assembly for permitting the camera to accept a large number of film sizes and formats loaded in removeable, light-tight film holders. The assembly is especially useful in adapting the camera for use with Polaroid-type film. The assembly includes a sliding frame which is attached to the mechanical movement means of the camera for synchronous movement with the aperture.
