Thank you Paul for the nice welcome...  I will try to be more specific with
my questions regarding med. / large format 3d photography with a view
camera.

    For MAXIMUM 3D EFFECT, I heard from a 3d pro, to shoot the following way
with a view camera.   Lets say you were shooting a statue of a person 12
feet from the camera...  So you take your first shot with the persons nose,
dead center in the ground glass (gg), next shot you move the film standard
over 65mm.......then move the front standard over far enough to view the
persons nose dead center in the gg again... so it would be less than 65mm.
How much less is a factor of how close the subject is.  This supposedly will
create a non keystoning "toe in" effect.  Is this desirable?  Has anyone
experienced any more WOW factor by doing this?  Any comments would be most
appreciated...

     I oversimplified a bit.. the other missing ingredient was to determine
the total travel range of the front standard, divide by two, then move the
front that much from center on each shot... so you split the difference,
instead of putting it all in 2nd shot.

    My other question ..... is there any benefit to doing 4x5 stereo
photography over med. format... I see the increase WOW factor from 35mm...
but my guess would be that med. format is big enough, anything bigger would
not create additional benefits due to the minimal magnification involved.  I
realize the 4x5 viewer would be a major issue involving prisms and / or
mirrors... and bulky due to the size of the chromes, but disregarding that,
assuming there was readily available 4x5 3d viewers what is the opinion of
some of you 3d enthusiast out there who have compared this already?  Thanks
again for your input...
