I have a huge collection of older photos (10 - 30 years) sitting in their envelopes, and I really would like to go through them to pick out ones to make layouts. But it keeps not happening, and I think I've figured out my roadblock. I'm afraid to use the "real" photo. I had thought that I should scan anything I wanted to use, and put the original away in an archive. While I still think that is a good strategy, the sheer amount of work that represents is keeping me from doing anything at all.
So here is my question: Is there a mount system that is safe to use on these originals? In most cases I do still have the negatives in the same envelope as the prints. Am I blowing this out of proportion?
