The Stereomatic 500 was much like other 50's stereo projectors except that it had a carriage and lens system designed for View-Master reels. Personal reels could be viewed with the wide range of viewers designed for commercial reels but for group presentations Sawyer's offered the View-Master Stereomatic 500 projector. 001 inch, well within the requirements of the mounts. The View-Master Personal film cutter cut the chips to a tolerance of. Because of the tight tolerances required by these slip in pockets and the way the images are arranged, it would be nearly impossible to properly cut the film with scissors or with conventional film cutters. The pockets had marks on them corresponding to the notches on the right and left images. Personal reel mounts were available with special pockets to insert the film chips.
offered a mounting service through mail order and similar services were offered by local dealers. Once the film was processed, there were several options for mounting the images in reels. Since standard slide film was used in the camera, users needed only to submit the film to any processor and request that it be returned uncut. Top view of the View-Master Personal stereo camera. The flash synchronization is through a nonstandard connector. The view finder is the direct view type with a bubble level visible in the frame, to ensure proper alignment. This dial rotates as shutter speed and aperture are adjusted to indicate proper exposure in conditions of bright sun, hazy sun, cloudy bright, and cloudy dull for dark, average and light subjects. There is an exposure indicator which can be adjusted for different film speeds (ASA 5-100). The Shutter speed is continuously adjustable and has labeled marks at 10, 15, 25, 50, and 100 with several unlabeled marks between these numbers. The aperture selector has a hyperfocal table that shows the "range of sharpness from X to infinity for the aperture setting, about 7 feet for F/4, about 6 feet for F/5.6, a little closer than 5 feet for f/8 and a little closer than 4 feet for f/11. The aperture selector is continuously adjustable and has marks for 3.5, 4, 4.5, 5.6, 6.3, 8, 11, and 16. The View-Master Personal is fixed focus with variable aperture and shutter speed. About half of the blank space is punched out with each film chip so that it can be handled by the blank area, to avoid scratching the image area. The View-Master Personal advances by 8 sprockets with each picture and, as with Realist format cameras, there are two unrelated images between the right and left images of a pair, but there are also two smaller blank spaces.
The A/B selector, aside from shifting the images up and down also adjusts the film winding mechanism so that when the selector is on "A" the knob turns counter clockwise and the film counter counts down, and when it is on "B" the knob turns clockwise and the counter counts up. This is accomplished by a "lens shift" mechanism which starts out in the "A" position to expose the bottom half of the film while the film is wound out of the canister and then in the "B" position the top half of the film is exposed while it is wound back into the canister. The View-Master Personal stereo camera uses 35mm film to produce 69 stereo pairs from a 36-exposure roll of film. Two views of the film chamber with the selector in different positions
