Performances of Held run through May 1.
According to the New York Times, Greenfield is onstage with the dancers during part of the performance, taking pictures of them at 1/2000th of a second. About 350 of the images are projected onto two screens as she takes them.
"I have no safety net," Greenfield told the Times. "This dance is happening faster than any dance I've seen in my life. It's coming at me from all sides, in all directions. It's pretty nerve-wracking."
Greenfield shot photography for the Village Voice from the 1970s to the early 90s, as well as photographing dancers in her studio. Her books of dance photography include Breaking Bounds and Airborne: The New Dance Photography of Lois Greenfield.
Held has its roots in a photo shoot Greenfield did with Australian Dance Theatre in November 2003. Her photographs were meant to be the basis for a new work, but Stewart became interested in choreographing for photography. "I had to create choreography embedded with a multitude of photogenic moments," he said.
