This may seem like a dumb question, but I've been known to ask them! I have been using 120 B+W film in my C330, and developing it on my own. The 120 film winds nicely on to my Nikkor SS reels. I just bought (by mistake) some 220 film. I'll use it, but wonder how I will get it on the reel since it will be 2x as long as the 120. I'm sure there is an obvious answer to this, but darned if I can see it!
