I wonder if anyone knows the capacity of 1 litre stock ID11 and/or D76? Ilford's fact-sheet suggests it it ten rolls of 36exp 35mm film:
while the Kodak fact-sheet suggests it is four rolls:
Any advice from someone with practical experience would be appreciated (and anyone who suggests I should "test, test, test" or "dilute 1:1" will be X&!*).
