For anyone who is interested...(posted 9239 days ago)Have just stated using ABC Pyro on 120 roll film, mainly Ilford PanF+.
Firstly, I don't know why I've read so many comments about how tricky and fickle it is. It may be for tray processing but I've not had any problems with roll film in a tank. Mind you it's early days! ;-)
What I did, when mixing the stock solutions, was mix each of the three stock solutions in distilled water at less that 25c. I made sure that all of one chemical was disolved before adding the next (only an issue with solution A).
When creating a working solution, I again use distilled water this time at 20c. I mix solutions B & C before adding A. I mix up around 100ml of solution MORE than recommended by the tank manufacturer. I add the working solution to the tank within a minute of adding solution A.
I invert the tank quickly during agitation but not aggressively. I also use the core to turn the reel. This done after invertions and after tapping the tank to release air bubbles. In the initial 30 secs I rotate the core clockwise, then anti-clockwise about 3 or 4 turns and then invert the tank. After that it's 3 inversions in 5 secs for every remaining minute.
At this stage I've used 10 mins at 20c but the negs are too dense in the high values and so I'm going to reduce development time a bit.
As far as safety is concerned, when mixing stock solutions I wear latex gloves, a dust mask and goggles. When mixing the working solution I wear latex gloves and goggles. In both cases I work slowly and carefully. I'll post more information about how I'm going if anyone is interested.
