But the drill is to make *soft* positive so you can get through all parts
of it easily for the negative. (See FotoDave, P-F #2.) If the positive is
"punchy" it's much harder to get a full scale negative, especially
separation in shadows & highlights -- or so goes the conventional wisdom.
However, your sharing these tidbits is most extremely pleasurable (so much
better you than I for the 88 hours in the darkroom). I trust you will tell
which was easier for the negative, the "dull" Bergger & Plus X or the
"punchy" tri X. (Perhaps another shibboleth will bite the dust.)
Meanwhile, how do you gauge the final negs -- got densitometer???
