[photo-3d] Velvia and Viewing Methods

[markaren@xxxxxxxxx]

Unfortunately, 1/3 stop increments ( or 1/2 stop for that matter) are
not possible with most stereo cameras. ( Can the S1 bracket 1/3 stops?)
And illuminated viewers like a Red Button will always seem to appear
brighter than common stereo projectors. I suppose a voltage regulator
could be used with a viewer to match a projector etc. It seems very
unlikely to match both illuminated viewer and projector requirements
when shooting Velvia with a stereo camera. I tend to favor an exposure
that would look best projected, and I like to use worn down batteries to
soften the halogen light in my Red Button. But even if the Red Buttom
and projector illumination could be matched, there is still a focal
lengh difference effecting stretch and squash.........so the 2 viewing
methods cannot be easily matched, nor would this be practical.
