P3D 127 Stereo Formats

[Ralph Johnston/Linda Sherman <copley@xxxxxxxxxxxxxxx>]

I have just made AutoCad drawings of the image formats for the 127 film stereo cameras.  It is posted on this web page down at the bottom:


http://www.ultranet.com/~copley/StereoNE/slidefmt.html

The Coronet/Nordetta format has a two full frame advance for 4 pairs / roll.
The Baby Rolleidoscop format has a 1.6 full frame advance for 5 pairs / roll.
The Stereo Hit format has alternate half-frame and 3 half-frame advance for 8 pairs / roll.

My next task is to shoot a roll of Ektachrome in the Rolleidoscop and mount the pairs in super-slide mounts for viewing in a Franka viewer, or projecting with twin Ektagraphics.

The StereoHit pairs, although nice, are too narrow to mount this way.  You would have to hand cut masks to mount them in 2x2's.  I don't have the original viewer.

The Coronet pairs could be cut down but I don't trust the quality of the single-element lenses.

Regards -Ralph
