[MF3D.FORUM:1338] Re: Larger aperture size for twin rig shots?

["Don Lopp" <dlopp@xxxxxxxxxxxxxxx>]

Paul T spoke of taking hyper pictures using a stereo base of 6 inches, 12
inches and24 inches while having a stereo window at 7 feet which is not
compatable eith taking pictures with a depth of from 7 to 10 feet. 90% of my
pictures are sharp from 12 feet to infinity  ( I  have stereo depth out to
about 200 to 300 feet ) sharp M F is that way- especially in a decent viewer
which is more than I can say about 35m m stereo ( my prejudice is showing. I
do not know of any words capable of describing M F but it can be great- just
ask anyone that  uses it such as Paul , Sam, Greg and the rest of us lucky
guys.
