Some Observations of Stereoscopic Projection

The Stereoscope is nearly a century old. Stereoscopic photographs were made almost simultaneously with the first practical photographic pictures, and stereoscopic projection devices for still pictures have been known for over seventy years. Motion pictures in relief, when viewed through red and green filters, one for each eye, have been shown too often to be now a novelty. — Fundamentally, stereoscopic vision requires that two eyes, related physiologically and psychologically, each view separately distinctly different pictures. Unless the taking, printing, projecting, and viewing of pictures are all done in such a way as to prevent the left eye from seeing what the right eye sees, there is no license to characterize the system as stereoscopic. This paper discusses several available methods for independent left and right eye vision.
