Here we go again....
Playing with my Paterson spiral I noticed it comes apart to wider for 126/127(?) and for 120 film.
A-ha!
Duly widened it, disappeared into the downstairs loo and loaded an old roll of B&W onto the spool (after plenty of swearing amid the darkness!)
Dropped the spool into my Paterson System 4 tank (can you see what's coming next?)...
And popped the lid on. Or more accurately didn't!
One thing I hadn't tested was that the lid actually fit the tank when the spiral had been widened!
Never one to be put off by common sense I threw my 300ml of dev and fixer into the tank and processed the roll, twiddling instead of inverting. Holding the lid down manually.
After fixing and washing I stood back to admire my handiwork!
Half of the roll had been buggered by light leaking in, and the other half was processed perfectly, until the top inch which had neither sat in the dev nor fixer.
Another photographic triumph!
To which end... does anyone in the UK have a 120 size tank they aren't using?
