Photography can be either the best representation of emotion, or the worst. Thats what i love about photography...you never really know what your going to get; Especially with a film camera. Capturing the emotion of real people is, i feel the most important part of the photograph. My favorite artist---
Dorothea Lange along with a few others that photographed the Dust Bowl really capture the feelings of the people. That is my goal as a photography student.

Another 'genre' of photography that i love is surrealist... Melting clocks and beds floating on the open ocean have always intrigued me. Its not so much that they portray the emotion of the portraits (above) but they have a sort of zen quality that portrays a certain thought or idea instead of a personal emotion.
