This app wirelessly links the video cameras on four iPhones. Ready, camera two!

People are making movies, commercials, and music videos using nothing but the cameras on their iPhones nowadays, but what about directing live TV? You know, the kind of thing where a guy in headphones yells at a bunch of little screens representing multiple cameras: “Ready camera one! Take one! Zoom camera two!” Now, with an app called CollabraCam, you can wirelessly link four iPhone, iPad 2, or iPod Touch cameras and direct their coverage like you’re Holly Hunter in Broadcast News.
