I have been heavily interested in 3D, be it watching or creating. Taking two photos and joining them together for 3D is ok, but you can’t photograph anything moving or take video that way.
My solution was to create this complex arrangement of mirrors. The final image is split into two, with the left and right images being shown top to top.
Using this I can take video, such as thsi
The process is complex as I have to convert my video from the cameras native format back to mpeg2 for use in Stereo Movie Maker then save it out as a calibrated left/right video.
