Build your own 3D dual camera mounting rails

Ritwika Mitra shows how to build your own dual camera mount featuring an adjustable interaxial distance for 3d stereoscopic photography or video. Ritwika is a high school senior, by the way. Cool young woman! She and her sister are also the founders of the non-profit Rennow.org.

The details begin at about 2:30 into the video. I built this but I also use a fixed mounting bracket that is simpler and smaller. At some point, I will post photos of my set up for 3D.

Amazing – Create 3D video from old 2D videos

This is an amazingly nice 3D video created by Dan Eckert as a conversion from 2D video.

How the heck does that work? As long as the camera is moving slowly left or right during the video shoot, you can create a fake 3D stereoscopic view by offsetting the 2D video by a few frames. Use the original video stream for one eye and the offset stream for the other eye – your brain sees this as three dimensional. The effect is amazing.

Youtube now provides a 2D to 3D conversion feature as well.
