[photo-3d] Wollenvere/Revensak

[ers <ers@xxxxxxxxxxxx>]

Just an FYI-- these lens boards don't interchange, though they look like they 
should. You can't stick Wollensak boards into a Revere without serious 
modification to the camera-- that is if you want the lenses to sharp focus at 
infinity. I've heard one trick to avoid remachining the Revere is to install 
-1 diopter lenses behind the Wollensak array. I've never tried it. If anyone 
has lmk if it works. I know one person who successfully installed a Wollensak 
board in a Revere, and he said it was a significant job, and he'd never do it 
again...
