Bill-

Thanks for the help, that makes sense.

This is my first experience with 120 film and I'm a bit confused. The film I have didn't come in any sort of protective container, it was just wrapped around a spool. Once I've exposed all of the film, should I just pull out the take up spool (which now has my exposed film wrapped around it) and put it into some sort of lightproof container to bring to my photo lab?
