Filmmaker James Cameron on penguins, arctic cold, and lowlight cameras

James Cameron wasn't near the penguins this time around, but he is extremely familiar with their environment. "When I went to Antarctica myself, I had a Nikon still camera adapted to the cold with special lubricants," he tells Popular Science. "I went to the South Pole and the film shattered in my hand when I tried to change it. I took a video camera, I wrapped it in a heating pack and it [died] in two minutes. I have a good sense of what it takes to take conventional equipment into that environment and survive."
