Sandy, do you think the change in A & B parts is affecting the development densities at differing tonal ranges in some of the above posts, or is it more a matter of dilutions and agitations? I understand why you have altered the A & B ratios for stain. tim
The slight increase in the amount of A solution serves to reduce oxidation, which in turn lowers B+F stain. Probably not significant if you are printing with silver processes.
