NBC has an unusually good online video of a K2 expedition—the 'Shared Summits' attempt, which was captured in Hi-Def.
Hi-Definition footage is really changing how I think of television. Previous to the technology, you'd need a virtual army to take a 35mm Panavision camera on a trip like this. Now, with tiny HD cameras, even a small expedition can return with theater-quality video that gives the viewer a vastly more real experience.
That makes it possible for us to see video like this: a fast-and-light team trying for a new route up one of the world's most dangerous and deadly peaks.
