Miguel was kind enough to gift me a bag of D76 powder last April. I mixed a stock solution (one 109g bag in a liter of water) and used it a couple of times in the recommended 1:1 dilution. I then stored the stock solution in a normal brown plastic bottle with plenty of air on top of it (ie, not vacuumed or marbles added to raise the volume to the top) and stored it at room temperature. Since I only use D76 for Tri-X shot at 400ISO, and 99% of the time I'm shooting Tri-X I push it, I never used the D76 until tonight, when I had a roll of Tri-X that I tried out in Peter's (now my) Contax T. I wasn't sure that the stock solution would last almost an entire year(!), so I diluted it 1:1 and did a leader test and it looked fine. I went ahead and developed the roll, and the negs look great! In fact, it looks a little
overdeveloped, but that's easily fixed. I still have about 200mL of the stock solution, which should be good to develop one more roll at 1:1, so we'll see how much longer it lasts!
