If you ever thought about taking 3D photos or video you are going to love this tutorial. It is based around the oldish Ricoh GX8, but you can adapt it to any camera you desire, as long as you can trigger them remotely. The general idea is quite simple, and here is the outline for it:
Take a two digital cameras which can be triggered remotely. Make a frame for the cameras with two compartments, so they are parallel to each other. Make/buy a Y splitter so you can trigger both left and right camera simultaneously. Put the left and right image together using StereoPhoto Maker. Make your own stereo viewer and enjoy your own 3d images.
