Am I the only one who has found this "anti-B" belief rather over done
lately?? I do realize that using 75% or more solution B does degrade tones
(they gets grainy and seem to loss shadow detail). But to suggest that no
"B" should be used is rather limiting. I find that if I aim for a 75% "A"
and 25% "B" negative, I see no loss in quality and a lot more flexibility
to "fix" or "reinterpret" the negative after development.

I have found the keeping of 6 or 8 different developers (to change grades)
a large nuisance, without any real advantage over reasonably limiting the
amount of potassium chlorate (part "B") solution. This sure keeps life
simpler!
