Good point. Many of us olde f***s have already edited things by throwing away the film that really isn't presentable, saving mostly the photos that mean something (at least to us) and have some redeeming artistic or technical value. And of course the way film worked there was some editing up front when taking the pictures too. All else is snapshots and cruft, which go with the family and go to garbage when nobody's interested any more. It's the edited collections, I think, that deserve consideration for preservation, not the vast pile of other stuff.

Even with digital, that happens. I don't shoot that many pictures, but since going digital shoot many more than I ever did with film (marginal cost of another shot is zero). But the edited & polished ones that go into "My Pictures" or elsewhere for further use are a vanishingly small subset of the total. Key for most archives is not just the pictures, but the provenance: can you prove when/where you took the picture and explain why it's significant? If you can't, it's a snapshot ibid. and don't worry about preservation.
