Although there are a few photo-conservators on Alt-photo, you will find
more of them on PhotoHist (where conservation discussions per se are NOT
welcome) and you will find *most* of them on the Conservation DistList
which also has neatly indexed archives and a complete directory of their
members, with areas of interests, etc.
The problem when you put a question to the wrong list is that you get
replies from non-specialists who mean well but who are not up to date on
the matter at hand. The old thiourea/phosphoric acid "magic" trick has done
more harm then good (in terms of long term effects) and this is well
documented in the conservation literature.
My Newsletter (see Web URL below) has info on how to access the
Conservation Distlist.
Finally, to the many who have, directly or otherwise on the Net, tried to
get advice from me and others on specific conservation problems of vintage
images, there are two main reasons for me/us to be evasive. One is legal.
The other one (related to the first one) is that no matter how hard you try
to describe a problem, your description is simply not good enough in 95% of
the cases. Don't worry about it because almost everyday I deal with
professional archivists and curators with 20+ years of experience and they
are in the same position. The problem is serious enough to be the subject
of an upcoming book and a course for museum people that will start next
year in Montreal.
For more info, contact me offlist.
