New York native Lois Greenfield is best known for her approach to photographing dancers in motion. Her atypical career started with a degree in anthropology and plans to become an ethnographic filmmaker. Instead, she started work as a photojournalist for local newspapers. After traveling the world as a photojournalist for several years, she was assigned to shoot a dress rehearsal for a dance concert, and the rest is history. In this program, she explains how she captures the essence of movement in her photos, her improvisational technique, and exploiting photography's ability to "slice time."
