Well, shooting on the street is a slippery practice, one learns to be invisible, to try to be present and in the right place at the right time, before people get a sense of your being there to photograph them. And I really developed this kind of invisibility for many years. But then I found myself walking around with this wide-lens wooden camera, which stood a meter and a half tall on a tripod: suddenly, people saw me, and my cloak of invisibility was gone.
