It is a little pretentious to cite influences.
Perhaps it’s better to acknowledge those photographers who’s vision has helped me see – Eugène Atget, Paul Strand, Harry Callahan, Aaron Siskind, Minor White, Walker-Evans, Henri Cartier-Bresson, Robert Frank, Kertész, Fred Herzog, Raymond Moore, Edwin Smith, Lee Friedlander, Fay Godwin and Andrew Sanderson.
For me, it really starts with Atget and continued by Walker-Evans with his lyrical style of documentary. If I was forced to pick out two photographers it would be these two.
