Photography Without Gravity
In this terrific video you'll see Canadian astronaut Chris Hadfield shoot amazing photos of Earth from the International Space Station using a Nikon DSLR and a 400mm lens. The photos are unreal, but what's even more interesting is the technical instruction he offers on how he gets the best results. Also, it's surreal to see him drop the camera, and watch as it just floats there unharmed. No tripod needed!
