I just managed to run a complete roll of Panf through my Hasselblad today with the dark slide in which shouldn't be possible I realise ... my old style A12 back has a problem which allows such stupidity unfortunately.
Is it possible to return the film to the original spool without the paper backing bunching up? ... I'm reluctant to waste the roll!
I realise it can't be done in the film back of course but is it possible in a change bag or a darkroom?
