Christine,
In the book reproducing Belloque's "Storyville Portraits" printed by Lee
Friedlander from original glass plate negatives, the introduction says that
Friedlander at first found the negatives too contrasty even for silver POP,
when exposed in the usual way in sunlight. Somehow or other, he figured out
that if he exposed very slowly in subdued light, the contrast came down into
range. According to these notes in the book, he printed some of these
negatives all day every day for a week or more using indoor window
illumination.
If that holds true, then it seems that exposing in full sunlight will give
the highest of contrast with this material while long exposures in softer
light will lower contrast. But other factors, like the spectrum of the
exposing light, may introduce another completely separate factor.---Carl
