Description: Nicholas Nixon: Nixon's been photographing the Brown Sisters since 1975, one photo every year, black and white, the sisters in one order. Taken alone, the photos are unexceptional but juxtaposed they're like a sedimentary rock, each layer distinguishable but really more valuable when viewed as part of a whole, an inconclusive meditation on time and relationships. Nixon's still shooting, too, even after a slew of major shows in 2005 (31 years) and a book out in 2007 (33 years).
