Hi Bob,(posted 9059 days ago)I don't know if this will be any better, but have you considered traditional metal film hangers and square tanks? You can certainly do up to a dozen at a time, or just one. You'd have to get them loaded, but that's fairly easy. I can even envision some sort of guide fixture where you'd hang the hanger on it, then funnel the film into the slot. These things have served large format people well for, I dunno, 75 years or more, and are plentiful on the used market.
