Here's another newbie question.

I plan to do some 5x7 B&W film development sometime later this year. I have never done any film development before, and obviously don't want to start with the 5x7. I have a 120 back for my 4x5/5x7 camera, and would thnk that would be a sensible format to start with, since it will allow me to check some new (to me) lenses I recently got at the same time.

I do not see myself ever doing a lot of film development, and if I do, it will probably only be 5x7. So I plan to use trays. Here's my question: will it work to develop the 120 in these trays, or will it curl up too much? I figure I'll want to experiment with times and such, and maybe even different chemicals (though maybe not that), so I would think that cutting the roll(s) of film into pieces in the dark and then trying each slice one at a time would make the most sense. Would they just curl into little rolls? Does my plan fail for other reasons? Or am I on the right track here?

I'd be grateful for any tips on the best way to go about this.
