stereo.thurston.us is a good source of info
Viewmaster would be awsome. I thought about that format, but I thought disk availability and hand-mounting would be an issue. I would definately give it a try now that I am more experienced with mounting and have more sources than I did.
I was happy to recently find a used TL-120 and intend to take some great stuff with it.
But the backbone of my stereo shooting has been the TDC Colorist I & II. The winding spool typically needs to be repaired or reinforced, and the focus/controls usually need a good CLA. But it's worth it because they're effortless to use and have the most consistently sharp and contrasty lens of any Realist Era camera. You won't find anything better for the money.
enjoy the tl-120 I love mine! Especially for indoor shots with my vivitar flash set at auto f11 and some astia 100f. The slides are almost too real! The people I've shown them too are amazed and a little frightened by them ;)
http://www.fresavolante.com/Home/Home.html that is making new reels and a company called Paramount Cords http://www.paramountcords.com/prodde...=PM-VMHSFM-PCF that is making an electronic flash adapter.
I have bought supplies from both of these companies in the last year (2012) so I can say that they are alive and well.
I was shooting Kodak Elitechrome 100, but now I have a roll of Velvia 50 loaded.
Disclaimer: I do currently use the parent company of Paramount cords as a vendor where I work, what can I say, they were willing to make something for me that no one else was willing to make.
Having one Mamiya C22, it struck me that it would be fairly simple to align two of them using the tripod mounts and a piece of tubing and make a highly capable stereo camera system which would use conventional processing
I have a Stereo Realist. It is big, heavy and a bit clunky to use, but it takes great pictures. The worst part is cutting the film and mounting the two shots in the slide holder. This is such a pain, I recall reading once that someone was offering to pay for someone to do it for them!
Several years ago I bought a pair of Oly 35RC's and a pair of the little Panavue hand-held viewers. The full size 35mm slide should give a a better quality, and the optics of the Oly's are well known. I have never gotten around to making the mount for either the cameras of the viewers. :-(
Taking a 3-D photo is very different from a 2-D --> the subject matter, composition, everything. So it is difficult to switch between the two. You have to be in the right mindset for each format.
I find that 3D is the exact opposite of normal photography in that when you take a 3D photo the more stuff you have in the photo the better, having stuff between you and the subject is even better.
