I wonder if he's tried making a Quad-a-scopic camera for us eyeglass wearers? LOL.

Stereo cameras are very cool. I remember when I was a kid my best friend's dad was a professor at Yale Forestry. They used to take aerial stereoscopic images of forests and such, and he would take us to look at them. It was really cool to look at them through the little viewfinders -- they looked so 3D. I might give it a try someday if there is an easy way to do it. I remember reading somewhere that someone made a stereo camera out of two hexar RF's...that would be interesting to see!

Ah, here we go, the RBT-S1
Very cool.

You can do it with one camera. You would need to make
a device to slide the camera left or right several inches
to make your second image...Displaying the stereo pairs
is another matter.

I studied air photo interpretation as part of my geography minor in college, so I spent a LOT of time looking through those little viewers!

The way aerial stereos are made is about as simple as it can get: They just use one camera, and shoot two frames a short interval apart. The forward motion of the plane provides the necessary stereo separation. There's no reason you couldn't use the same principle by shooting out the window of a car, for example, although it might make subject selection a bit restrictive...

Hi Rob-- Yes, I've done this using a Paramender, intended for shifting a TLR on its tripod for parallax correction. I just mounted it horizontally instead to achieve a stereo pair in two successive shots with an Olympus Pen half-frame. Of course I chose static subjects. At the time, I was trying for minimal contrast and shapes to see how well the stereo effect could stand on its own.
