ABSTRACT:
Apparatus and method of projecting photographic images from a first film onto a second film. The images on the first film are made in a scan camera and represent a series of aspect views of a subject photographed by the scan camera. The apparatus includes means at a first location for mounting the first film adjacent to a first lattice. Light is directed through the first film and the first lattice as the first film and first lattice are moved one pitch line relative to each other. The light is then directed through a projection lens and a second lattice and onto a second film spaced from the first film as the second lattice and the second film move relative to each other one pitch line. The first and second lattices can comprise Ronchi gratings or can be first and second lenticular screens.
