Bob - I quickly skimmed the article you refer to below. My confidence in
the accuracy of comment plummeted because the author states that
selenium is a "transition metal" which it most definitely is not.

None of your references comes from Kodak. A fine point, but quite important
in my view. Lets look at your references:

The Alt list is not a reference worth trusting a hundred percent of the
time, no list is. It is a mailing list and granted, there are some people
that likely know a few things, but the list should not be trusted to prove
anyone's point. I have talked with some of these list "experts" and it is
quite clear many know very little about photochemistry or photography, for
that matter.
