Shooting 3D With One Camera and a Chemistry Stand


If you want to get a good 3D image there are a few ways to go about it.  You could wait until 3D cameras get released, set up two identical cameras with identical lenses next to eachother, or simply do what John Edgar Park did and use the same camera twice.

The process, says Park, isn't as complicated as people make it out to be.  "The idea behind shooting 3D images is to take two identical photographs offset horizontally by approximately 2.5 inches. This is the average interaxial distance between human eyeballs."

The rig he made is fairly simple, but very cool.  It's essentially a chemistry stand that's been modified a bit to hold a camera mount.  Take a picture, slide the camera over and take another and you're good to go.

From there you'll have to do the usual post-processing tricks to make it all work - crop the images, line them up, and work the appropriate Photoshop magic.
