Here's an article and quite a few examples on making 3-D still images. They're really incredible - much better than the random dot type. I'm dying to try this, and hopefully I'll figure it out. Or wait until the author explains (as he mentions he'll do in an upcoming article).

Found this site which seems to have lots of info, and lots of examples from all over the place. I wonder why I haven't seen this before...

I wonder too, since ive seen this stuff since i was a kid
here's a shot i posted on RMNP: 3D
My ESS shot is no longer up. The process is very simple, shooting identical scene at a slight separation (usually about 1/30 distance to closest object) but requires a worthy subject.
Some very cool stuff is being done with 'lenticulars', single photos in 3D using tiny lens to differentiate the different views. See Tim M's repsonse to my rmnp post for example.

Thanks a lot Stan. I know stereoscopic images have been around for a long long time - I've seen a bunch, especially the random-dot-stereogram kind that got popular again in the 90's. And given the amount of photo-based web browsing I do, I was just surprised I hadn't run across the apparently large numbers of people that are doing their own. Funny how that works sometimes.
Anyway, the only drawback to these, that I can see, is that the image separation forces you to cross your eyes a lot more than you have to with random dot. I suppose that's why crossing was chosen, rather than going out-of-focus like the usual random-dot method. (You can cross your eyes a lot farther than they spread when focusing in the distance.)
I've never heard of lenticulars....something more to look up.
Wish I'd read Stans post first. Now I have to schedule a visit with an eye Doctor. There goes my Moab trip! Do either of you guys have stock in the eye care buisness?
(just kidding).
