Some people say that Robert Frank or Garry Winogrand and some other well-known “street” photographers were not street photographers, but documentary photographers. I think they were both. Clearly, they enjoyed traveling across the country, walking through cities or towns and making photographs of what they saw or encountered. Sometimes they interacted with subjects, often they did not. Were they documenting America - a time, places, a particular vision? Yes. Did they pick particular subjects to “document” - as did Winogrand in his books Public Relations or Animals. Of course. But I believe the essence of their work was to be out in the world, on the street and making photographs. To me, that is street photography. Bystander by Colin Westerbeck and Joel Meyerowitz is a wonderful book on the history of street photography.
