I have been obsessed with 3D, ever since I was given my first View-Master in the 1970's. I've been an obsessive collector of all things stereoscopic ever since, and I've been taking my own 3D photos for the last 20 years or so.
It works reasonably well. I set this up because I wanted a portable system that could use passive glasses, and the results aren't bad. I will post a more detailed account of it soon.
It's ridiculous! To use it, you need to connect it to the "video out" socket of the camcorder (so it can synchronise to the frame rate of the video). The active shutters significantly cut down the amount of light reaching the camera, so the image is very murky. Depending on the camera, there is quite a bit of vignetting, so you need to zoom in slightly to compensate, and worst of all, the left image is noticeably smaller than the right image! Back in the 90's there was no easy way to correct this. These days you can correct the alignment in the computer, but the video quality is so bad, there's no point in going to all the trouble. Still, it's an interesting piece of 3D history...
