I know two ways of getting the film out of the canister, but what are the pros and cons?
1) Open the canister at the bottom with a bottle opener and take the spool out. (I use this now)
2) Use a leader receiver to get the film leader out and wind the development spool directly from the canister. (I stopped using this as I suspect this method to make small scratches on the film when unloading the canister).
