New to Rodinal and I see 1:25, 1:50, 1:100 and more. Ok I know the more diluted you do the longer it takes for the development time. Is the longer developments only advantage is more control of the process. Why would it be more advantageous to use a longer rather a short development time. Ok the next basic question, Could I use regular tap water for my Rodinal since I do use Distilled with my Fix. Not that I am trying to be cheap on the first stage but semi cold water out of the tap is easier to work with.
