Thanks for all the help, guys! I finally managed to shoot my first few frames today. Considering that I had no idea what I was doing, I was pretty happy that two of my six frames actually had an image on them. LOL. Seriously, it's so different. Between figuring out how to load the film holders, working with a quirky lens in need of some TLC, remembering that whole sequence of exposing the film, and figuring out tray processing, I consider 33% to be a pretty decent success rate. And it might have been an even 50%, but I'll never know -- I dropped a sheet on the way into the developer. Woops.
