Agreeing with the others... also, with some film developers (Diafine, Divided D76 and a few others) you shouldn't use an acid stop. I prefer to use water (less stress on the film) but at the most, a simple solution of Photograde Citric Acid. I really don't like the smell of the acetic acid so for me it is a personal thing. Everyone has a different way of doing things and as DJ states... as long as your consistent you can't go wrong.(posted 8386 days ago)
