Subject: duplex super 120 stereo camera film back

yes, lost 1/2 roll due to skipping / reading the back incorrectly


the other thing I discovered was all shots were out of focus bar a couple of close ups. 


now its either a) lenses need calibrating (exposure matched fine) or b) the scale of measurements are in meters or parts there of? 


so my guestimate of 10 feet was in fact, not in feet - and I'm prettu good estimating.

I've never handled one, but I'd expect it to be marked in
meters, not feet. That's easy enough to check with a ruler
and a piece of ground glass (or cellophane, or waxed paper,
or thin cloth, or . . .)

Can we please move the Duplex discussion to another forum?  It's not a medium format camera.  It takes 120 film, but it's a Realist format camera.  Perhaps you could move the discussion to the photo-3d list or the Realist list.

You should also check that the roll back has the same focusing plane as the plate back. Is it a genuine Voigtländer back?
