Seeing color

[P3D Dr. George A. Themelis <fj834@xxxxxxxxxxxxxxxxxxxxx>]

I received a B&W stereo slide with the instructions to put it in my stereo
projector and use a red filter over one lens and will see color.

I did that and sure enough, the slide becomes a color slide.  I can see
light red, skin color, brown and a bit of green.  Not saturated colors
(a.k.a. "Velvia") but nevertheless there is color.

I have read the Land's (of Polaroid fame) articles in Scientific American
so I was not surprised but it is still impressive to see colors out of a
B&W picture using nothing else but a red filter.

This has nothing to do with 3d, the two B&W chips are flat (one is recorded
with a red filter over the camera) but the demonstration uses a stereo
mount and a stereo projector.  Also, I used the red filter from a pair of
anaglyph glasses.

If you are taking B&W slides this demonstration is worth a try!
