Magnum photographer David Hurn’s documentary photographs are distinguished by their quiet observation and remarkable insight. “Life as it unfolds in front of the camera is full of so much complexity, wonder and surprise that I find it unnecessary to create new realities,” he writes. “There is more pleasure, for me, in things as they are.” Hurn fell in love with the state of Arizona, in the United States, and made several trips back between 1979 and 2001, turning his eye to ordinary Arizonians in their daily life, their schools, exercise classes, holidays and their landscape. His new book entitled Arizona Trips contains more than 150 photographs on the subject. The British photographer is here in conversation with writer Sir Christopher Frayling.
