How do you do this? I have a collection of my father's fiberbased photos that are dry mounted to cheap matboard. It was done almost 50 years ago and some of the mats are discolored and they take up too much room, besides. The photos are not of any great value, but I guess I'd feel guilty just throwing them away. If I can reduce the volume, that would be great. (They are 11x14 on 16x20 boards.) I know that this is possible as a friend of mine had an AA photo redone. The guy that did it kept his technique a bit of a secret, but I think it involved a very high temperature in the dry mount press. I have tried this with some success, but would like to gather as much info as possible before I start.
