Joel Meyerowitz, one of the great street photographers of the twentieth century, talks about his time watching the photographer Robert Frank taking pictures ("and it was all so physical, balletic and magical"), to his own time, shooting for over 50 years, with most of his work being shot in New York. He explains his views on photography as well as his need to get into Ground Zero, after 9/11, to document the wreckage of the Twin Towers being cleared, where he shot for nine months.
