Walker Evans’s idea of photographing people on the train without them knowing was a good idea. The pictures on the subway show peoples reactions. Everyone seems to have the same emotion or expression. Everyone has such a serious face. It makes you think what are they thinking, why is their face so serious. There is one picture of a man and lady sitting next to each other. Their faces look as though they’re staring right into the camera lens. I think it’s pretty interesting how he captured people in their natural state opposed to when people hear let me take a picture, they pose or smile for it.
