"DiCorcia rigged strobe lights to scaffolding and trained his lens on an "X" he taped to the sidewalk. From 20 feet away, he took shots of Nussenzweig and thousands of other unsuspecting subjects. Later that year, diCorcia exhibited this image under the title "#13" at a Pace Wildenstein gallery show called "Heads" in Chelsea. The photographer said multiple prints of Nussenzweig's picture sold for about $20,000 each. The picture also was published in "Heads," a book that sold several thousand copies, diCorcia said. Now Nussenzweig, a retired diamond merchant from New Jersey, is snapping back at diCorcia — and at the right of photographers to secretly grab pictures on the street and sell them — by suing him, Pace Wildenstein, publisher Pace/MacGill and unnamed distributors and sellers of the image and the book."While I go around snapping pictures of all kinds of stuff, I do agree with Nussenzweig here completely. I feel that due process is required with one is publishing and selling photographs with other people's pictures. Although, none of the tabloids (and the paparazzi for the tabloids) take permission from their subjects. So I guess this case may have repercussions beyond just the "Heads".
