From Smiling Seals to Exploding Landscapes, Photographers Journey to Earth's Most Dangerous Places For "Extreme Exposure"

1 of 10

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," on view at the Annenberg Space for Photography from October 23—April 17, 2011, honors incredible nature photography—and the renowned photographers that produce them—by exploring the relationship between the photographers and their subjects.

Here, a male walrus flicks his tusks on the ice, sending a warning to the half-submerged photographer. The giant tusks of adult walruses can grow up to 90 centimeters long. Females prefer to congregate in Russian waters to the east, so the walrus population in Norway, where this photo was taken, is primarily male much of the year.
