I just stumbled over this, Wellesley Art Professor Asks, What Do Your Snapshots Say About Your Family? an interview with my college photography professor, Judy Black. I thought it was fitting, since I'm spending my evening working on the photos of Ana and Kate that I just took last week.
"Photographs look so honest and truthful," she said. "But it all depends: All photos have the problem of interpretation. It's the person taking the picture who's doing the editing, not the camera. If you were writing in a journal or painting a portrait, you would be much more aware of the editing."
