The Chinstrap penguins were photographed from a small ship near Monroe Island in the South Orkney Island group, Antarctica. A Nikon D300 and a Nikkor 70-300 mm VR lens at 300 mm were used. The exposure was f/11 and 1/1000 sec (ISO 3200) -- fast enough to freeze the motion of the airborne penguins even though they and the ship were moving in opposite directions. Image by Irwin H. Segel.
