Diet and filmmaking legend Peter Jackson's given us another insight into the making of the Hobbit movies, and this time he's talking about his envious collection of tech. Filming with no less than 48 Red Epic cameras at 48fps in full 5k resolution might sound fantastic, but it hasn't all been a bed of cotton candy. Two 3D cameras need to be mounted at the same "interocular" (the inch-or-so distance between your eyes) which is impossible given the size of the Epic and its lenses. The team had to hire specialist firm 3ality to build a rig where one camera shoots the action and the other is pointed vertically at a mirror. Those who would love to shoot with an Epic should also beware that the cameras naturally desaturate the action to such an extent that the makeup, costume and set design teams have to over-color everything to look natural in post production. For more interesting facts, head down past the break to catch the video in full, and try not to imagine how many years bad luck you'd get if you broke one of those mirrors during a key scene.
