    Retrieving film from canister to develop.

    What's the best way to get at the film? Do I need a special tool or is there an easy way to prise the canister open and get the film?
    Thanks

    You can purchase and use a leader retriever, You can check your camera manual to see if you can set it so it doesn't fully retract the leader, you can attach some double~sided tape to some thin card (about an inch wide ~ poke it in the light trap and try to catch the end of the film on the exposed sticky surface) OR..................
    you can (only in the dark!!) either remove the end of the canister with a bottle opener or similar tool, or you can (carefully) stick a screwdriver into the light trap and rip it open
    All this time, and still only IRIPN!

    That's what I do (in the changing bag, pre-loaded with the disassembled dev tank & spiral).

    They used to sell a special tool for levering off the end caps of the cassette, but I found it was just as easy to use a medium size flat blade screwdriver. Squeeze the light trap and there is a gap into which it is easy to slip the blade, one quick twist & the end cap is off. Then pull the spool & film out of the open can, cut off the half width leader (it's a nuisance with Paterson spirals) & load the spiral. Tear off the inside end of the film from the spool when you come to it, but SLOWLY as rapid tearing of glue can cause phosphoresence which can fog the film! Spiral onto centre, into tank (the right way up), lid on, job done.
    If you're not living on the edge, you're wasting space

    The Ilford cassette opener is still available for sale. Google for it. It's a bit like a bottle opener. I used to prise the cassettes open using a knife, but the cassette opener is a tad safer and easier

    And I have / had the first one takes a bit of getting used to. I bought mine after watching a mini-lab operator use one to recover leaders before tapeing them to the plastic card that used to pull film through the processor. With practice it can be used in a split second.

    I've got one of those, but what I use is a Swiss Army knife - the bottle opener works perfectly, and I then trim the leader with the scissors.

    Any bottle opener would do, wouldn't it? The benefit of the leader retriever is that you don't have to do it in the dark, though.

    No, but you run an increased risk of scratching the film by pulling it through the light trap (grit gatherer) again.

    Grit gatherer? I don't let grit anywhere near the canister in the first place, and have never scratched a film in the three years I've been processing my own. I'm reasonably confident that Ilford doesn't put grit in the canister on my behalf.

    Is the risk the same as that of having someone's eye out with a stick, or an angry swan breaking your arm?

    I prefer loading the spiral direct from the casette. I've never had a problem with scratching yet.
    Can't be a***d with a signature.

    As I always used a proper darkroom,I tapped the cassette on a work surface to open it, or sometimes squeezed the sides of the cassette to realease one end plate.

    I agree that opening the cassette with a bottle opener is the cleanest and quickest option. If, though, you want to retrieve a leader rip a 1in strip off an old glossy print and give the glossy side a good licking so it is properly damp. Feed it gloss side down (facing the core) into the cassette and wind it in by turning the spool. Once it is being pulled in you've 'hooked' the film, so just pull it out again to see the leader wiggling like a trout on the end of it.

    It can take a couple of goes, but its cheaper and more sporting than buying a proper leader retriever.

    Yes, I've done that, but it never worked on those Kodak cassettes with crimped ends.

    It's risk enough, and in my mind, a completely pointless risk - perhaps over only three years you've not seen it, but believe me, it can happen. I've never seen the logic of doing it that way, given that if you leave the leader out you've got another set of controls to follow to ensure you don't reload a used film into the camera... that's two potential risks against none doing it the other way, so for me it's a no-brainer. YMMV.

    I seem to recall that Ilford cassettes used to be much easier to open and indeed to re-use, but maybe that's just me looking at the past through rose tinted specs!
