When a photograph captures a moment of action—like this male walrus sending a warning to a creeping photographer—it seems to freeze time, preserving something astonishing that has long since passed.
"Extreme Exposure," a group exhibit at the Annenberg Space for Photography, features arresting imagery from five unique photographers who work on the edge of wildlife, climate and environment. Clyde Butcher, Paul Nicklen, Michael Nichols and Donna & Stephen O'Meara have made careers documenting rarely seen moments in the life of our planet.
