Hi Lee,

I would advise against exposing these conserved pages to excessive heat.

There are alternative lights sources that can be used that are far 
cooler and the photographger can simply reset his film type and/or 
color balance to compensate - or they can go to a flash unit that will 
minimize both heat and light exposure to the book.

If you can find out the name of the conservator who did the original 
treatment you should contact them for advice. There are also several 
very qualified book and paper conservators in North Carolina. You can 
go to www.aic.stanford.edu and use the free  guide for conservation 
services to locate qualified conservators in your area.

Cheers
Dave

Subject: Photographic Heat Exposure

    Hello.  We need to photograph a book in our archives, and this book 
has had
extensive conservation work done to it.  The few pages (less than 10) 
that
we wish to photograph appear to be encapsulated in Japanese tissue paper
using wheat paste as the adhering agent.  During the photographic 
process,
the page being shot may reach 80+ degrees Fahrenheit if additional 
lighting
is needed.  I realize this is not ideal, and am taking steps to slowly
acclimatize the book before the photo shoot.  We will rest the pages 
every
few shots, and closely watch heat levels.  My question is this, does 
anyone
know what these possible elevated heat levels will do to the wheat 
paste and
Japanese tissue paper?  Thank you.
