Lighting is so important in computer "3D" graphics because they're missing the
third "D"! With a flat 2D image, which is what the computer guys call "3D", the
only depth clues you have are the shadows and light modelling. With
stereographic 3D (referred to by the computer guys as "phoney 3D" or "cross-eyed
geek 3D"), you have actual depth perception instead of inferred depth. Of course
this is not to say that lighting isn't important. It's one of the most important
elements in ANY good photo. All I'm saying is that I don't think that a stereo
photograph needs to be lighted any differently than any other photo. Other
opinions?

A sudden semi-related, past-my-bedtime thought: Could anybody who shoots 3D with
a flash comment on whether or not they get the "red-eye" effect that is so
common in one-lens flash photography, or do the different angles offset it?
