Projection of the stereo films is made possible by the Nord Projector Conver¬ ter. This is an optical unit housed in a metal case and supported on an inde¬ pendent base, so that it is unnecessary to attach the unit to the projector at all. In use, the projection unit is placed on the same table with the 16mm pro¬ jector at a distance of approximately one fool ahead of the projection lens. File beam of light passes through this unit on its way to the screen. The exact position of the unit is not particularly critical. The projection unit does two things. It polarizes the light independ¬ ently for the right and left-hand images and at the same time it overlaps these images in correct registration. Two simple adjustments are provided so that by turning two knobs the images can he aligned independently in both the vertical and horizontal positions. Ordi¬ narily once these adjustments are made for a particular projector they need not he repeated unless, of course, the set¬ tings are disturbed between showings. A unique feature of the Nord 3rddimension svstem is a test him which is supplied with the projection kit. This him has a circle and a cross photo¬ graphed thereon and positioned so that it is only necessary to manipulate the knobs until the cross as seen on the pro¬ jection screen is centered on the circle. Since these two images are the same size this is very easily done; it is impossible to make any mistakes since the him can¬ not be incorrectly threaded. The test him will operate equally well whether run through the projector right side up or upside down and regardless of whe¬ ther the emulsion position is toward the screen or toward the light. Pictures made with the Nord 3rddimension attachment must be projected upon a special screen, which is included in the kit. The members of the audience view the pictures through Polaroid spectacles, also supplied. Movies made by this system have a terifhc impact that is impossible to de¬ scribe adequately. The results are so dif¬ ferent from ordinary movies that it is not like looking at a picture at all. The effect is more like looking at a real scene out of a window. While the stereo depth is completely satisfactory, in all fairness there are two limitations which must be mentioned. Since the standard 16mm frame is divid¬ ed in half by the dual images, this re¬ quires a screen new and different in 7(i American Cinematographer February, 1952
