3D viewing requires two images from slightly different perspectives, much
like having two eyes in different parts of the head. Shooting two of the
same image from a TV would give you a nice 3D image of your TV set, with a
flat image on the screen. There are different ways to capture
different-perspective images, including cameras with two lenses, or two
frames from a film with lateral movement.
I recently saw a series of short videos by Michael Betancourt where he
provided something called chroma-key glasses to view them, which made
different colors appear to be nearer or farther from each other. It's a
very striking 3D effect. I also used the glasses to watch some regular
broadcast TV, and amazingly, some of the images were also in 3D, although
the spatial relationships were sometimes surreal (a red shirt appearing
behind the person wearing it, for example).
I believe Michael is on the list, perhaps he can explain how it works.

will work, Is it possible to shoot two of the same image from a TV, the same
way you would shoot in 3D (two cameras) put them together, color them and
somehow make a TV image 3D, There's probably a fundamental aspect of 3D
technology that I am missing here but It sounds nice... no doubt I'll try
messing wiht it.
any pointers
