I'm going to buy another negative carrier and file it out for full frame 120 prints, but I've been wondering how I would hold the film in place. It's okay if it's the middle negative in a strip of three, but if it's one of the end ones, how can you hold it flat in a filed-out carrier?
This would be negs 1,5,6,10,11,15 for my Mamiya 645... in fact I probably managed that without even trying
