That is correct. The ability to see 3D is not related to the ability to see color. While it is popular to remember the red green glasses of the 1950s (The colors are actually red and cyan) most projected film uses polarized light to separate the images. Depth perception is an illusion that happens in the brain. It can be affected by such things as cataracts, or lazy eye. Or the more obvious a missing eye. Those "can u see the shark" painitings that used to be in the mall shops, where developed from tests used to determine this theory. They are properly called single image random dot stereograms (SIRDS.) They are also known as Julez patterns after the researcher who did the early work on this in the 1960s. I think this has gone way past the original intent. I made a mistake in understanding the new process. I have been corrected on this.

As for the old process, using the red/cyan filters, I have that on my website <http://www.delectra.com/jporter/> As I actively (Even as recently as this last December) take 3D photographs, the feedback I have, even with the direct steroptican viewer is that a number of my aquantances indicate that they are unable to see the 3d effect in the images.

I look forward to seeing the reviews of the new process.

Er, why? It shouldn't require color vision, because the filtering is done *before* the light reaches the eye. Color-filtered 3D might look more natural to the colorblind than to the rest of us, for that reason.
