Photographer Joel Meyerowitz has spent the past month taking photographs of Ground Zero for the Museum of City of the New York archives. He had also been shooting pictures of the Manhattan skyline and the World Trade Center Towers since 1981. The last photo he took of the skyline was shot four days before the September 11 attacks. Several of these photos were recently featured in the New Yorker magazine. They'll also be on exhibit at the Ariel Meyerowitz Gallery in Manhattan beginning November 1st.
