Stereograms! Make Your Own 3D Camera for $15 or Less
If you happen to have two digital cameras, you can skip some of the steps, like getting the film developed and scanning the pictures. I was able to get my hands on a second camera; I found that butt-end joining got the lenses close together. I also tried side-by-side, using some optics posts and attaching to the camera tripod mounts. Unfortunately I did not have a third camera, so I can’t show the full rig.
Here is a laser table stereogram. I tested this on a few people, and not all could get it to work. But I can, and that’s good enough, for I am the benchmark for many things.
Also, you can see that the two pictures appear to diverge from each other, an example of the leaning tower illusion
