I wanted a more economic solution to investigating cameras for light leaks other than shooting a whole roll of film and developing. In the past I have loaded a roll of film, shot a few frames in bright conditions, then using black tape cover the seals and shoot the rest of the roll as normal. If the camera leaks then the first few frames would tell me. But then I thought of, in total darkness, cutting a strip of film. Placing it in the back of the camera, take a shot in bright conditions and developing that strip. Just to see if the camera leaks light. I didn’t want to waste developer on just one strip of film so I was thinking of what I could use as a developing tank.

I tried developing in small trays, in the dark but that was not comfortable at all standing in pitch black for 15 minutes. Then it dawned on me. Why not use the film can as a developing tank! All I need to do is put the developer in the film can (1ml or Rodinal), turn the lights off, take the strip out of the camera, put it in the film can, put the lid on, turn the lights back on and continue. The film can is light tight and it worked a treat!
I had two jugs next to me, one for stop, one for fix and in the dark I would stop and fix after developing.
After I had established my camera had no leaks I started to do all kinds of experiments. One of which was after developing and stopping I would turn the lights on and fix. I was amazed to see the results.
A whole roll of FP4 later I had Pushed, Pulled, Stand, agitated like a cocktail amongst other things and had a bag of fun in the darkroom.
Just a great way to try new things if anything else.
