Rodinal and short shelf life
I developed a roll in Rodinal yesterday that has been on my darkroom shelf for over a year. It was a disaster The liquid was quite dark but knowing that Rodinal had amazing keeping qualities I committed the roll to it Grossly underdeveloped at 10 min 1:50 at 71 degrees. I immediately checked the camera and everything was in working order. The developer is labeled RO9 Connect Chemical Product and Services for Comparad KG In all fairness the fine print does say it only has a 6 months shelf life after the bottle is opened. This is not the Rodinal I remember I am setting up a shot for a roll of clip tests covering the normal 10 stop range for future developers before committing a roll to a new developer. . Meanwhile I will get a batch of amber glass bottles to decant the new bottle of Rodinal into 2 oz full capped batches as I do with both HC110 and Claytons F-76. Both of which are claimed to have long shelf lives, but better safe than sorry.
