I am searching B&W films for my newly acquired 10x20 banquet camera. First place contacted is jandc photo to see if they can cut their Cirkut roll film for me. The answer was no. Shall I just order a roll and cut it myself? I have concern about the film flatness. Order a box of 12x20 and just cut it myself? I have cut papers before, but not films. Any suggestions from other ULF users for this new comer? Thanks.
