>>3270597And here's a closeup of the drum with some film mounted to it. These are 6x17 slides. I mount a lot closer now and fit much more on there per mount, this is an older image.
You sandwich the film between the drum and some clear mylar, using a special mounting fluid to remove all newton rings. The mounting station has a heavy roller on top that holds the film down and helps push out the air, but it still takes a lot of practice to get right.
