"First, unless you ( or anyone else) are a famous, in demand, high value photographer, then it pretty much doesn't matter what happens to them after we are dead. No one will care enough to bother with them so, into the trash they go."
If that had happened, no one would know who Vivian
Meier, Mike Disfarmer, Eugene Atget, or Diane Arbus were.
Secondly even photographs that do not have great aesthetic or monetary value are worth a great deal to historians. They tell stories about the ways people lived, how people dressed, how they lived, what they valued.
