>>3806694Do you even understand how a medium format film works? 645 and 6 by 6 use the rule of vertically, just look at the two Hasselblad magazines the A12 and A16.
Pentax 6 by 7 and then the various other 6 by 8 and 6 by 9 all the way up to the 617 roll the film horizontally.
Years ago, I made friends with a guy doing IMAX work in Vancouver he gave me a couple hundred feet of unusable film, at least for the IMAX camera which screams by the frame at an ungodly rate. I reuse that film in a double perforated 70 Magazine from Hasselblad
