Subject: [pure-silver] Plenachrome film development
I have a student in my darkroom class who will be bringing
in to develop a roll of Plenachrome 120 film that was in an
old box camera he just purchased. Since this film is 50
years old or more, I expect it is fogged. Would it help to
add some Benzotriazole solution? I have some on hand and the
container says that it is used for paper, but could it help
the film? We have no idea how long to develop the film in
Xtol, but I expect we can't overdevelop it. We don't
expect this film will yield much, but what the heck, we have
to try.

More: Since the film is orthochromatic you can develop
by inspection under a dark red safelight. That will allow
judging the development and will be educational to boot:-)
