After searching through APUG I haven't found a thread that provides a collection of info on this subject. I wasn't sure where to post this either.

My question is:
What tips do you have to ensure the best storage and preservation of your favourite fine art photographs. How do you best look after them to ensure the best archivability?

Matted
Unmatted
RC paper
Fibre based
toned
untoned
etc...
etc...

Can you post your favourite informative website addresses that cover these issues?

Thanks again APUG.
Kind regards,
Nicole
