" Light is meaningful only in relation to darkness, and truth presupposes error. It is these mingled opposites which people our life, which make it pungent, intoxicating. We only exist in terms of this conflict, in the zone where black and white clash."
Black and white are the colors of photography. To me they symbolize the alternatives of hope and despair to which mankind is forever subjected.
The whole point of taking pictures is so that you don't have to explain things with words.
