I just had a great/stupid idea. Put a 35mm lens on the front, attach it to a DSLR, then connect it to a computer and a printer...put the whole works inside that gargantuan thing...then tell people it's a really old Polaroid.
I don't think you could call it a field camera either!
The film holders were for 20x24 sheet film, at least the ones we found. They did have an old darkroom set up but all the items were in poor shape and who knows when it was used last.
Made for an interesting day and now I'm just waiting for the wife to get home and see it in the middle of the living room.
In case you feel like shooting...here's a link to some 20x24 sheet film. However, it's 10 bucks a sheet lol. This box of film is four times the price of the camera!
