I've seen reference to people using BZT as an addition in their developer to help control fogging in bromide papers. I've seen "add a pinch", "add a little", "add some"... but nothing exact.
Can anyone recommend an exact quantity to use (or at least to start out) with PF's 130 Devloper? I've got some old Brovira paper I would like to try to print on this weekend, but I don't have much of it so I would like to minimize waste in testing.
Your thoughts are appreciated, but your shared experience would be better.
