Since I love instant photography and I need a bit more of a push to get into large format, I was hoping to start shooting some of the larger 4x5 Fuji FP-100C and FP-3000B. But apparently the Polaroid 405 holder only takes the smaller 3.25x4.25 film...? 1) What sort of film holder do I need to accept these larger pack films, since my camera is a Toyo D45M? I assume whatever I need works primarily like your standard LF film holder, except that it has rollers to pull the pack film through. 2) Anyone got one they want to sell me? Of course, if I get an answer to #1, I can just make a WTB ad in the classifieds.
