A method for making a low bandwidth stereoscopic hologram of a subject. Vertical parallax is eliminated to reduce information content. The remainder is transformed to a larger area thereby reducing the information spatial density of the resulting hologram. A narrow horizontal aperture is the means for limiting vertical parallax. The resulting hologram is suitable for television transmission. To view a stereoscopic image of the original subject a real image of the aperture is formed from the resulting hologram. An observer looks through the aperture image as if it were a window to view the stereoscopic subject image.
