I should add that the neg I printed was quite dense so the paper is clearly no longer a grade 3. Well that is to be expected of course with paper of this age.

How much sodium bromide and/or benzotriazole would one add to a developer to help the fog? The paper, to my eye has a little fog and lowered contrast. The posted scan is a litte off, its not quite as flat as that in the actual print but it could benefit from some anti fog agent. I wonder how much do you use?
