I have developed 2 rolls of Kentmere 400 in Rodinal 1:50 at 20 mins and fixed with Ilford Rapid Fixer that I didn't realize have long expired and gone bad. The negatives came out very thin, even the leader, so I put them back into the same fixer solution (not realizing it's bad yet) and fixed for 10 more minutes to no avail.
The next day I went out and bought a fresh bottle of Fomafix and tried to refix a piece of leader once more to see if it darkens any further. It didn't, so I didn't proceed refixing the entire rolls.
I have 2 more rolls waiting to be developed but I would like to identify the exact cause of the problem so I don't ruin them too. Is it all the fault of expired fixer or could it be something else?
- The films I developed have been shot almost half a year ago and were stored in fridge.
- The film itself is fresh and is hand rolled from a 100ft roll with which I had no issues before.
- I made a test of expired Ilford fixer afterwards and it cleared a piece of leader in about 5-7 mins. As far as I understand, the fact that it clears the film doesn't mean it fixes it properly.
- Rodinal I use is Fomadon R09 (with dilutions of 1:25/1:50, similar to Adox Rodinal). It have expired in 2015, but I have used it half a year ago last time with no issues.
