Abstract: The essential conditions for producing pictures in stereoscopic relief are two: First, separate pictures must be made from different points of view, corresponding to the two eyes; second, each eye of the observer must receive its appropriate view. No compromise with these fundamental requirements appears possible. If stereoscopic projection is to be achieved in such a form that a large group of observers may simultaneously see the projected picture in relief, the distribution of the appropriate views to the two eyes must be accomplished for each observer. There are two places where the distribution may be made: the first is at the observers' eyes; the second is at the screen on which the picture is projected. If the first method be employed, two separate images must be provided on the screen, and every observer must have means for directing one image to the right eye and one to the left eye. If distribution of the images is to be made at the screen, two images are no longer sufficient. Theoretically an extremely large number must be provided, a separate one for each position that can be occupied by any eye in the audience. Several methods of utilising the parallax panoramagram method are discussed. It appears that from the theoretical standpoint the problem of relief projection is entirely soluble, and experimental tests of still picture projection have been successfully made. Practically, the solution of relief projection of motion pictures will depend upon the use of apparatus involving excessive speeds of operation, great multiplicity of taking or projecting units, projection screens containing minute ridged reflecting or refracting elements of extreme optical perfection, projection lenses of extraordinary defining power, microscopic accuracy of film positioning, and photographic emulsions of speeds at present unknown.
