Stereoscopic Film Viewer Shows Scenes in Color
Three-dimensional views in color are provided by the novel stereoscopic instrument pictured in use at the right. Color films are mounted in disks that are placed within the apparatus, which is provided with a small lever at the top for moving successive frames into place before the dual eyepieces. Each disk contains a different set of film pictures. Small pieces of ground glass behind the film insure an even light on the scene viewed.
