I have some prints that I want to dry mount but I have no experience with dry mounting (I'm trying to be more archivally aware with all my processes)...

I am not sure dry mounting is good for long life of a photograph, even many here state opposite. One more problem I didi not mention befor is how you think to reframe your dry mounted photograps when you cannot remove it, or can do it with good cost and risk, and than dry mount again and set the same question again.

The best is acid free mat in front, acid free foam at the back (thick around 1/8), mechanical means to fix the photograph, no glass if no fly problem.
