Here is a bit of stereoscope info:
Modern stereoscope devices can be seen here:
I think that this should work for me. I can create larger (8x10? inch prints) left and right images then view them through the older metal stereoscopes in an exhibition or for my self. Combined with strong documentary photography (not gimmicky photography) the art created could have an extremely strong effect on the viewer.
Here is the the last link, to a book one of the eBay sellers referred me to.
Principles and Applications of Photogeology
The eventual set up might look something like this. I would of course mount the 2 photos, left and right eye to some kind of board to make it easier for the viewer to handle. I could have 10 different large stereographs for them to view, heck I could have 100.
Note* I wonder if making stereograph photos would be easier to do 100% digitally? Digital 3D cameras, prints etc. Then view them under the same device, or directly on a monitor. Maybe so., not sure. Not sure I want to go that way thou, it is kind of cool to work with the older tools, just like with platinum prints or wet plate photography. There is something truly beautiful in bringing those techniques and cameras back to life. Victorian photography, today!
