Walker Evans was a photographer and photojournalist born in St Louis, Missouri. His photographs focused on the documentation of the effects of the Great Depression and were taken for the Farm Security Administration. Evans' pictures were taken in black and white and featured different places and people who represented the era of the Great Depression. His portraits and photographs were taken from a entered angle, from above, some from below and other angles. After this era, he did a black and white portfolio of Brown Brothers Harriman & Co's offices, since he was passionate about literature and writing. Reading and writing were his motivations for his photos and so was the understanding of people and the effects of big changes.
