Walker Evans.

Walker Evans is a renowned photographer, known for pushing the boundaries and influencing today’s photography artists.
His first impulse was to become a writer. However after travelling around, due to the fact that his parents had separated he realized writing was a passion of his, but not something he wanted to pursue, perhaps it was not challenging enough for him? He resented the American lifestyle, but ended up returning there anyway.
When he discovered a vest-pocket camera in 1928 he decided on a whim he would have a go at becoming a photographer, little did he realize he was about to change the history of photography....
Photography was not necessarily Evans' calling like writing, but it was something he thought he could do.
He began by challenging two other photographers who had also influenced the medium very much, Alfred Steiglitz and Edward Steichen. Evans' wanted to break out of the way that people saw photography; he dabbled in advertising, but was against the idea of perusing any of these conventional forms of photography.
Although Evans' had rejected the way that Stieglitz and Steichen had worked one persons advise stuck in his mind, "An artist should be everywhere felt, but no where seen. Further more art must rise above personal emotions and nervous susceptibilities. It is the time to endow it with pitiless method, with the exactness of physical science." Some of the major influences on Evans' were writers and painters. Evans' strived to be a perfectionist, but not for the public, for himself, he never thought himself good enough. Evans' approach to photography was for it to be nothing but the truth. He worked on capturing segments of time. Because of this distinguishable way of photographing it meant that Evans' photographs were easily recognisable from other photographers at the time.
After living in poverty and striving to live Evans' became part of the group known as "farm Security Administration". This group of photographers were renowned for making great work during the depression period, their work reflected images of how the poor people were living, and this allowed Evans' to do what he did best. True photography. Working with sunlight only, no manipulation of the images and mostly his photographs were based solely on luck.
Walker Evans changed the way we see photography now, and has been a huge influence on other photographers around now.
