Endangered Species Light Up the Empire State Building

Between 9 P.M. and midnight on Saturday, the southern face of the Empire State Building became a giant projection screen filled with images of a snow leopard, a manta ray, and other imperilled land and sea creatures. The event, “Projecting Change: The Empire State Building,” devised by Louie Psihoyos, the executive director of Oceanic Preservation Society, and the filmmaker and photographer Travis Threlkel, was a union of art, activism, and ambitious publicity stunt, designed to call attention to the plight of endangered species.

From a viewing party on a rooftop at Twenty-Seventh Street and Fifth Avenue, the videographer Nathan Fitch and the photographer Matthew Pillsbury, who is known for using long exposure times, captured the projections unfolding against a clear night sky.
