• Most of my fellow students don't pop open the canisters to develop, could I tape the bulk roll to what's left in the canister? sure I've heard that.

    Yes common practice. Ask a local processor for used cannisters - they only bin them. Most of the processors cut the film - rather than open the cannister - so you have a small length of film poking out. Just tape your film to it and load the cassette. I prefer the 3M Scotch Magic tape, thin enough not to foul the felt light trap but easy to peel/tear when you take the film out for developing.

    If you use "used" cassettes just check the felt light trap before loading film for dust/fluff/crud. I use a piece of the 3M tape to dab any crud off the felt. I find I can re-use them 3-4 times before the felt start letting light in.
