Abstract
A light weight, compact, stereoscopic apparatus in the form of a lens assembly that can be removably attached to a conventional still motion picture or television camera as an integral unit in place of the normal lens so that a camera may be conveniently converted to three dimensional photography. The lens assembly when used results in superimposed stereoscopic records in color, which superimposed records are of the same size, and when viewed through suitably selected filters are in full relief and color, but when viewed without filters appear as a conventional two-dimensional view.
