Shark Cage, Marshall Islands, 1998

Photo: Shark Cage
"Safely behind bars, photographer Bill Curtsinger and his assistant, Eric Hiner, photograph themselves by a remote control as gray reef sharks close in.

"'They were so aggressive,' says Curtsinger, 'that I used my camera as a shield to keep them from sticking their heads in the cage.'"

—From "Testing the Waters of Rongelap," April 1998, National Geographic magazine

Long Exposures

When making long exposures, use a remote release to avoid camera movement. If you don't have a remote release, use the camera's self-timer.
