There is room for a decent 35mm stereo 3D projection system becasue the digital proejctor diffusion is going more slowly than expected. And it is going to be too costly an approach for many cinema opertors. Sadly the Technicolor adoption of the over/under system is not helpful in this context. They have done nothing, as far as I know, about the major problems of the sytem: It's not bright enough, it's easy to proejct pseudoscopically, and there is asymmertical corner darkening becasue of the intrinsic nature of lens coverage. It's a zombie foramt. Bringing back the dead to kill the living. Thanks for your kind words.

Can't get an adequate interaxial separation, except for extreme closeups, out of one lens. Also going to a high field rate with a single sensor just does not work becasue the iamges have to be captured essentially simultaneously. Electronic giants like Sony need to learn a lot more about stereo 3D before they can offer good products. Looks like their announcement was premature.

They use multiple rigs or cameras throughout the shot to sculpt the various elements of the scene. FredFred27 in LIve-Action has the right idea.

I honestly didn't know about the 20 times higher etc., but I do know you do see much better, much sharper with two eyes than one. Whatever is going on with muxing and demuxing for stereoplexing all of the various approaches I have seen lately produce similar results and the reduction in horizontal resolution is not apparent. Neither is there an apparent reduction in depth resolution. I don't know why. You know you are correct in most of what you say.

The discussion about non-Euclidean space representing how we preceive the visual world is intersting but I don't think this is currently a hot topic in psychology. The position I now take is that the mind is a black box and stereo compostion is best determined empirically and subjectively.

I was just there. At the North Shore is a place, Hanalei, with both Beach and Caves. Also, they have a lot of coastal fog / mist there right now in the Fall. :) Thanks. George Hi Lenny,
