I submit that the resolution in a 35mm Kodachrome 25 transparency is better
than any 3" contact print.

I thought we were talking about the usual stereo formats, why bring up some
virtually unused formats?

Agreed. There's even more limits on stereoscopy!

What I understand is that the emulsion in the transparency image was burned
by the very light that was reflected from the real objects that the image
represents. First generation.
The emulsion in virtually any stereo print was not. Second generation.

Come on! RE-EXPOSED? To what? Not light! Because there's an extra bath it's
second generation? Developer, reversal, color developer... there is no
second generation- I just can't believe that there's an argument at all...
how'd I get sucked in? Is Tom Hill going to chastise me, too? 

Remember when 3D was fun?

HEY! Now you've gone TOO FAR! I'm never responding to PHOTO 3D again! Maybe!
(what if the "original scene" was a photograph in a magazine?)
