For all you photography geeks out there.
Light field cameras were developed 15 years ago at Stanford and required a roomful of computers tethered to a super computer. The Lytro is the world's first consumer light field camera.
Unlike a conventional camera that captures a single plane of light, the Lytro camera captures the entire light field, which is all the light traveling in every direction in every point in space. Since you'll capture the color, intensity, and direction of all the light, you can experience the first major light field capability - focusing after the fact. Focus and re-focus, anywhere in the picture. You can refocus your pictures at anytime, after the fact. Click anywhere inside the pictures in the Lytro gallery to see the results.
You can pre-order for delivery in SP12, be advised this camera is currently only Mac compatible.
