A friend does this very well, with an unusual setup. He purchased an old process camera from a print shop that had
gone to flatbed scanning. He removed the old film back, and modified the front piece where art was held under glass to
where a piece of art could be held flat.
That's how the camera I mentioned started, but not old. I got a process camera maker to modify one of their beds. We
hung the back end from the reinforced concrete ceiling and rested the front on a frame also holding a vacuum copy board.
The actual picture taking part was a Durst 5x7 enlarger head hung in a custom made saddle from the now overhead "bed"
and fitted with4x5 film holder back and Zeiss enlarging lens with shutter in front.
Couldn't use a regular process camera as the copy holders were way too small.
A ff 35 digital with an old film era 50 macro was fitted to the back standard, and he added halogen lights. His work
is ad close to perfect as possible. Price was cheap. Process cameras are large cast iron things, very stable and free
of vibration, but hard to move without a truck and some husky guys, so print shops are usually willing to let them go
cheap just to get them out of their hair.
Not all were cast. The one I used was heavy sheet metal in an incomplete box, a "C", with another piece formed into a
zig-zag welded down the center of the "C". Very rigid, but lighter than a casting. Just as well, as we had to remove a
window and wall on the third floor to let a crane swing it in. :-) When it's years of useful life were over, the had to
cut it up to remove it.
They were built to enable front and back to be perfectly square, so software adjustments not required.
Yup, no alignment problems.
Don't know how many are still in the wild, though.
Darn few, I'll bet. Used to be every press shop had one.
