For the past three years, Stacey Baker has been photographing women's legs in New York City and posting the pictures on Instagram. The women are all strangers she met on the street who agreed to pose in front of a nearby wall. Only their legs are in frame, yet from this single starting point, the kaleidoscopic diversity of women in New York is revealed. The ease of making pictures with a cell phone has sparked a revolution in photography; Stacey's body of work is perhaps the most powerful to come out of a cultural moment of technology, fashion and people watching.
