D76 mixing error
While mixing up some Kodak Hypo Clearing Agent, I realized that I did not follow the instructions properly when I mixed up my first batch of D76 developer.
I dissolved the D76 powder into 3L of water at 55 degrees Celsius, but forgot to add the other 0.8L afterward.
I guess I should have realized something was wrong when the mixed developer didn't come close to filling the second 2L accordion bottle, but at the time I just rationalized that the first accordion bottle must have stretched beyond it's nominal capacity.
Anyway, I used 650ml of the D76 to develop 2 rolls of 35mm and other than some slightly yellow spots (drying marks? residual chemical?) the negatives seem to have come out OK. (I'm hoping the HCA might help eliminate those spots.)
I'm about to develop my first B&W 120 roll and wanted to ask if I should add perhaps 0.63L of water to the remaining D76. (Since I've already used 0.65L/3L or about 17%, I'm thinking I should only add 83% of the 0.8L I was supposed to add initially.)
P.S. Do I need to bring the D76 or the water up to 55 degrees Celsius if I do add some water?
