First, I have never done 3D or studied it extensively, so the following is
based mainly on casual reading!
I did experiement with a gadget that I got from Porter's Camera Store in Cedar
Falls, Iowa. This gadget is a mirror arrangement that fits in front of the lens
to create two images on one frame. My experiment was to use this in the
darkroom on my minilab to print wallet photos in a 2-up cluster. It showed
promise, but because of size, focal length, and lack of ambition, I never
followed through with it to what could have been a successful conclussion.
It's my understanding that the two cameras should be the same distance apart as
the human eyes for a realistic image. Further, the focal length of the lenses
has an effect on the separation distance. (Please reread my first paragraph!)
I've seen the antique stereo viewers and cards. The viewers have lenses in
them- whether it's just a slight mag lens I don't know. But that may make your
"short-arm-syndrome" less an issue.
I would be interested in hearing more about your stereo escapades.

There *is* pure-silver related question here ---
Have any of you done B&W, film 3-D images? Just as the digital wave was
arriving I bought a second Contax G with the idea of making old-fashioned
"stereoscope" images. I never completed the project, but eventually I bought a
second 45mm lens and built a side-by-side 2-camera rail. I stalled at that
point --- the Contax uses an electrical shutter release with a bizarre
connector, and I haven't yet created a second release that I can connect in
parallel. (The point is to be able to do "instantaneous" 3-d images of my
dogs.)
Have any of you done B&W stereoscope photos? Do you have any
recommendations, warnings or images you could share? That might get me moving
again!
I do not yet have a stereoscope or viewer. I know you can do this simply by
using a "wall" or divider between the right and left images, but I and my
friends are old enough that a little optical assistance is needed for normal
reading distances. Recommendations?
Thanks.
Myron
