[courtervideo] shares an instructible with us on how to build a mirror rig to take stereoscopic pictures with one camera. We’ve had the thought “couldn’t you just do that with some mirrors?” when looking at a dual camera rig. Well, as we all suspected, you can. There are some advantages here, a single click gives you your 3d image or video without any post processing, and unless you just happen to have an extra camera lying around you can save money there. You do however lose some resolution compared to two separate cameras. This setup could actually add some steps if you were wanting to interlace your images for viewing on a 3d tv.
