Shoot Now, Focus Later: A Little Camera To Change The Game
Just when you thought you had the latest in camera technology, along comes something new and shiny and ... rectangular.

The Lytro we received to demo is about four inches long. It's called the Lytro, and it uses something called "light field technology." In short: You shoot now and focus later.
NPR's resident photo expert, Keith Jenkins, explains: In a nutshell, he says, this camera captures not only the color and the intensity of light — which is what normal cameras do — but also the direction of that light — from every possible angle. Still confused? We are, too.
The best analogy came from Lytro CEO Ren Ng, who made a musical analogy. Let's say you like a band, and they're great live. But say you want to record them. You generally don't just stick a mic in the middle of the room and hope for the best. You record each band member — and sometimes even their instruments — separately in a studio. That way, when you're mixing it all together, you can control every element.
So think of the live band as a point-and-shoot camera on automatic and the studio recording as the Lytro.
