Adding some contrast to p/p is not in itself problematic. P/P has
tremendous contrast control, between the two actions of the metals,
whether you use pot ox, chlorates, or h202. When you are in the 8/4,
9/3/ 10/2, 11/1, range, that extra boost may well make the difference
between a good print and a flat print. We all know how bad a flat P/P
can look. Some of my best images and prints, came out of 9/3 negatives. >>
Gary, don't you find the h2o2 method unperdictable while the chlorates add
exxecive"grain to the image
