ABSTRACT:
An apparatus and method of making a parallax stereogram, i.e., free vision stereogram, and particularly for the accurate registration of a plurality of film images in order to ensure stereographic reproduction. Each film frame having the image thereon includes marks which are used in a projection printing apparatus to register the image in a desired position. The registration is accomplished by mechanical alignment according to the mark or by optically sensing the mark. A comparator-servo can adjust the film frame to the desired position. After registration each film frame is exposed onto a photosensitive material using a movable line grid. A lenticular screen is superimposed over the developed picture to form the stereoscopic photograph.
