Mr. Jones said, re the difficulties of near-object stereo vision:
>>
The problem is, what do we do about this as far as photography goes? While
we can mimic the way our vision works for distant objects, it's another
thing entirely when we get close up. Maybe there isn't a natural way to
photograph close objects in stereo...
>>
Folks can probably tell I have no experience with projection, the most
difficult and limiting circumstance of stereo viewing. So here's a
scenario:
An angry man is standing in front of me with a handgun pointed directly at
my nose, the end of the barrel is about one foot from my face, his arm
fully extended. I can see a full moon just over his shoulder.
In self defense, I pull out my SLR with a 35mm lens, at a tiny aperture
and held in a rock steady hand. I take two perfect exposures, each 35mm
to left or right of the gun barrel axis. My adversary runs away.
Now the question. Will I be able to set up any situation where I can
project my 2x2 pair, seat myself in perfect ortho-seat position, with the
moons 70mm apart (my interocular) on the screen, and experience my peril
exactly as it appeared at the moment of my crisis, without "too much
depth"? A prize to the simplest explanation of why not, if not.
Bruce
