The problem with vernacular photography is that most photos are only interesting for about a quarter second. There's also a tendency to admit photos to the display that should have been passed: If this picture of a plump woman in a mini skirt standing on a doghouse is interesting, why not include the one taken seconds later, slightly out of focus but with a better expression?
Culling discarded vernacular snapshots is often an illusory form of artistic discovery. The reason I know this is because over the years, aside from a few shots of historical interest, I have only found one bona fide amazing photo. It's framed and on display in my house, and I never tire of it. I share it with you here.
