40 years as a keen amateur photographer here - not that it means that much but -
Its a rather different skill than drawing, etc., but it is surprisingly difficult to get a “wow” picture like some of these people do on a regular basis.
Even in the case of a revealing portrait that LOOKS like it could have been taken by Joe Blow with a point&shoot - well, Joe Blows rarely take such pictures even when they try. It just ain’t that easy.
It is that easy. She’s not one in a million, she’s more like one in a hundred photographers. Her great talent was access not photography.
Marc Hauser is as good, but you likely never heard of him.
