Of all the photographs in The Americans, I think there were only two or three photographs where I did talk to the person, but most of the time I was completely silent, walking through the landscape, through the city, and photographing and turning away. Well, that is my temperament, to be silent, just looking on... What I liked about photography was precisely this: that I could walk away and I could be silent and it was done very quickly and there was no direct involvement.
