The trick is to take it of the same area exactly, use a tripod and all the same color/focus settings on your camera so things line up better.

Then put the left picture on the right and the right hand picture on the left side by side.

how would you do it with one camera in our tanks, considering the movement, would that not affect it?

Yes, you wouldn't be able to do it with a fish, or anything moving at anything quicker than a snail's pace. (Hmm.. I guess snails will still be okay)

Unless you can rig together a setup where you've got two cameras kind of taped together side-by-side, and get them to both use the same settings and take the picture at the same instant. THAT would work for fish, etc. and the distance apart would be fairly good too.

Stereo photographs are actually fairly easy, as you can read from other messages above. I've got a whole university degree where I did a huge amount of work analyzing stereo airplane/satellite images of land to do measurements of building heights and all sorts of stuff. Very neat, when you get into professional uses of stereo imagery. But that's a whole other.. uhh.. course.

Take care!

Sure Ryan.

Explains a thing or two.

Hmmm... now this is getting me all into taking a stereo image tonight.. probably of my Toadstool. Will have to see how it goes!

I can see those "hidden image" 3-d things without any trouble, but I don't seem to be able to focus my eyes on these images. Even with the finger trick, I can't overcome the refocus as soon as I try to look at the monitor.

Anyone have any other tricks to "see" these images?
