light field camera technology
In short, Lytro is developing a new type of camera that dramatically changes photography for the first time since the 1800s. Rather than just capturing one plane of light, it captures the entire light field around a picture, all in one shot taken on a single device. A light field includes every beam of light in every direction at every point in time. Experimentation in this field started in the mid-1990s at Stanford with 100 cameras in one room. Lytro’s innovation is making it small enough to fit in your pocket. Really.
