In Fig. 8 the ilm (12) has been advanced so that a frame (26) having a right stereoscopic image thereon is centered on the lens axis while the filter (16) has been revolved one hundred eighty degrees from the position it occupied in Fig. 7. It is noted FIG. 5 — Bell & Howell 16mm Filmo camera with stereo alternate frame selector. The camera mechanism is coupled with the gear train which drives a 180 degree shutter in front of the beam splitter. that, in Fig. 7, the outside of the semicylindrical filter (16) is presented to the lens (14) while in Fig. 8 the inside of the semicylindrical filter is presented to the lens (14). Moreover, the same axis (20) of polarization which, in Fig. 7, extended upwardly and to the left, now extends upwardly and to the right. Thus the image (28) on the screen (18) may be seen with the right eye only by a viewer wearing standard Polaroid spectacles.
