Well, that's what I'm doing, except my times double at 68 degrees and I
stick to the 1:15 of the Edwall as suggested.
I shoot filtered at N+ one, which is specifically two stops over exposed,
with one as a filter factor; and develop N+ two to obtain a negative in the
1.65 to 1.95 range that prints long and with time for manipulation under the
light for silver; and for Pt ... gee, I don't know, yet. But I get the
numbers.
A great comment Anchell makes in his DR Cookbook is: The old masters
substitution for patience in their development by inspection cannot be found
in any of the filmdevelopingformulas. (I may have paraphrased.)
