While there are plenty of advanced digital movie cameras, most of them aren't really designed for the modern realities of movie making, where computer-generated effects are seemingly ubiquitous. You'll still have to bust out the green screen if you want to put those real actors in a digital world. Lytro might have a better way, though. It's introducing the Lytro Cinema, a movie camera built with digital effects in mind. Since Lytro's light field technology captures a massive, 3D picture of the environment (755 RAW megapixels at up to 300FPS), you might never need a green screen again -- you can accurately determine the objects you want to keep in a given scene.
