Kent Kobersteen, former Director of Photography of National Geographic "The pictures are by Robert Clark, and were shot from the window of his studio in Brooklyn. Others shot the second plane hitting the tower, but I think there are elements in Clark's photographs that make them special. To me the wider shots not only give context to the tragedy, but also portray the normalcy of the day in every respect except at the Towers. I generally prefer tighter shots, but in this case I think the overall context of Manhattan makes a stronger image. And, the fact that Clark shot the pictures from his studio indicates how the events of 9/11 literally hit home. I find these images very compellingÑin fact, whenever I see them they force me to study them in great detail."
