The week I was wondering why you would use a STOP in development, and with STOP I am referring to the Amaloco S-10 Citric Acid stop I use. My 80ies photography guide says to use stop, but is quite unclear about why to use this acid stop. With Efke film I read to be very careful with stop. But why not with my Kodak TMAX100 or TMAX400? Feels like I am destroying the grain for some reason. So can't I just wash the film with water for about a minute and then fix instead of using this 30 seconds citric acid stop? Any pro's and contra's from the old skool developers? Thanks.
