Hello everyone,
New to the forum and to B&W developing. I've recently developed 2 rolls of Ilford FP4 at its normal 125 ISO and both rolls have a lot of white debris/spotting on them - please see the attached scans. The negatives similarly look cruddy with dark spots, I've taken photos of these on my phone so excuse the quality.
I'm using HC-110 at dilution B for 9mins 20degC, Ilfostop for 30secs, Ilford Rapid Fixer for 3mins, then the Ilford style wash - 5, 10, 20 inversions then final 5 inversions with Ilfotol. I would mention that my HC-110 and Ilfostop I had bought 4 years ago but hadn't got round to using so were unopened until using them now. The Rapid Fixer and Ilfotol are newly purchased.
I've been mixing my chemicals in tap water which in this area is fairly hard.
Doing searches on this and other forums I'm trying to figure out is it 1) a lack of rinsing? 2) not long enough fixing? 3) using tap water for the chemicals? I can purchase deionised water (unfortunately not distilled as such) but then do I just use this for the final rinse or for all the chemicals - developer, stopper and fixer?
I would be very grateful for any help and advice.
Many thanks
