PURPOSE:To obtain photosensitive paper which produces a stereo-scopic feeling by coating the surface of paper in specific grooved surface structure with photosensitive emulsion. CONSTITUTION:Mountain-shaped grooves with an angle b'bc'=theta deg.<30 deg. are formed and the surface is coated with photographic emulsion. When an image formed on this photosensitive paper is viewed at a distance of about 30cm, an image on left-side slanting surfaces of the mountain-shaped grooves is viewed with the left eye and an image on the right-side slanting surfaces is viewed with the right eye respectively; and those images are viewed one over the other because of the visual nerve, so that a stereoscopic image is seen. For the purpose, images photographed by a twin-lens camera at two right and left slightly different angles are formed on the right and left flanks of the mountain-shaped grooves and viewed, so that the stereoscopic image in the real state is formed.
