I was given some old enlarging paper today. I am assuming that it will most likely be fogged (at least a bit). It is ilford ilfobrom and AGFA Brovira (grades 4 &3). I have read that Potassium Bromide can be added to developer as a fog restrainer. I currently have a bottled solution of 10% KBr. How much should I add to 1 liter of developer?
