The Galaxy Planner’s roll film records pages list only 12 frames each, but that means 2-3 pages work for 24 or 36 exposure rolls of 135 film. Medium formats will fit on a single page for 6×17 6×12, 6×9, 6×7 or 6×6 formats. 6×4.5 format will require a page and a half, unfortunately. (Daniel J. Schneider)
