Originally posted by WPRESTO I would sometimes not wind the film entirely back into the canister. You can easily feel when the leader releases from the winding spool and stop.... If you plan to reuse the canister ... in the dark you pull the film out slowly for loading into a developing tank, then snip it off leaving perhaps half an inch protruding from the canister .... Then you can tape the end of a bulk film roll to that piece to get it pulled into and started on the spool within the canister.
I never rewound right into the canister (I call them cartridges). There was a school of thought that the slot in the cartridge is more likely to let light in if it is not filled with the film thickness. But an opposing school of thought said that the film substrate acts like a light pipe that leads light into the cartridge and therefore it is better to wind it right in
I always transfered the film cartridge to and from its black plastic outer container as quickly as possible, and yet I have seen transparent containers (not Ilford or Kodak). Moreover there was a photo shop in London that took in film for delveloping; when they did they promptly took the cartridge out of its plastic container and put it up on a high shelf with the others waiting for development - about 3 inches under a flourescent light tube!
Anyway, I recall that of Ilford and Kodak cartridges, with one of them and not the other (I forget which) you could push off its lid (the knob end) with a fingernail and push it back again after reloading with bulk film. It seemed lightproof afterwards. But I bought some cartridges that were designed for reloading from bulk; they are plastic and the end kind of screwed on and off.
