ABSTRACT:
Apparatus for providing three dimensional effect transparencies. The apparatus includes a camera including mounting means for retaining a photosensitive assembly at a predetermined location, and a movable lens. The apparatus further includes a movable support means for supporting the object whose image is to be taken, and further includes the photosensitive assembly. This assembly comprises a layer of photosensitive material, a line screen having regularly spaced blocking portions spaced by transparent portions and a transparent spacer disposed between the material and the line screen. The camera has a central axis with which the photosensitive assembly is aligned and the lens and the support means is movable along respective paths which extend transversely of the central axis. A three-dimensional effect transparency can be produced by placing the object at a number of spaced object locations and for each position, aligning the lens with the object and the intersection of the central axis with the assembly, and opening the lens to expose a portion of the photosensitive materials. The number of object positions is sufficient to substantially completely fill all photosensitive material segments beneath the blocking portions of the line screen.
