During his time aboard the International Space Station, astronaut Chris Hadfield has taken and shared some of the most amazing photos of our planet on his Twitter account. And in this video clip, he explains how he snaps those beautiful photos of Earth, and the wonderful camera equipment at his disposal.

Most of us will probably never have a chance to visit the International Space Station—at least while it's still in orbit—but that doesn't make seeing the unique challenges that face photographers 230 miles above the Earth any less fascinating. [YouTube via PetaPixel]
