Quick-N-Dirty Film Removal

Previously, whenever I've been developing my own 35mm film, I've always used a manual-rewind camera, and deliberately made sure not to wind all the film back into the cannister. This meant it was nice and easy to get the film from the cannister onto the dev tank spiral, as there was no faffing about trying to get the film out of the cannister. You just made sure there was always a wee bit hanging out.

Now though, I've been using my new and super-cheap Nikon F75, which has an automatic film rewind on it. This is great, because it saves you having to wind a daft wee crank for ages. However, it has the downside that it sucks the film all the way back into the cannister. I've read about various techniques for getting the film back out, but those involved special film extractor tools (I don't have one), or hacking the cannister to pieces (not so easy in a dark bag). I decided to try and find some more "quick-and-dirty" ways of getting the film out, and I stumbled across This Page via google.

The technique, which was brilliantly effective, involved using a strip of dymo tape, sticking it inside the cannister, and using the sticky side to pick up the film and pull it out. For those of you unaware, Dymo tape is the old-skool plastic tape used for embossing letters onto, used before the days of laser label printers and stuff (See example).

Here are the simple stages required:

  1. Take a strip of dymo tape, approximately 10cm (4 inches) long.
  2. Peel backing plastic off, exposing sticky adhesive.
  3. Push piece of tape into the film cannister through the opening slot, with the sticky side facing in towards the central spindle.
  4. Once the tape is in about 7cm (3 inches), you'll start to feel it jam. Pull the tape in a little further by winding the film spindle.
  5. Firmly (but not too hard), pull on the tape that's left outside the cannister. This should pull the end of the roll out through the opening slot.

For those of you worried, the adhesive on the dymo tape shouldn't damage the film at all. For starters, the adhesive only touches on the backing film, not on the emulsion side, so the emulsion will not be damaged. The tape only touches on the first 10cm (4 inches) of the roll anyway, which will usually be exposed to sunlight when loading, so will be no use anyway.

Works a treat!
