Black and white are the colors of photography. To me they symbolize the alternatives of hope and despair to which mankind is forever subjected. Most of my photographs are of people; they are seen simply, as through the eyes of the man in the street. There is one thing the photograph must contain, the humanity of the moment. This kind of photography is realism. But realism is not enough--there has to be vision, and the two together can make a good photograph. It is difficult to describe this thin line where matter ends and mind begins.
