Recently Lytro unveiled, the first Lytro consumer light field camera which is going to change the way Photography was defined till date.
The Lytro light field camera captures all the rays of light in a scene, providing new capabilities never before possible, such as the ability to focus a picture after itís taken. The pocket-sized camera, which offers a powerful 8x optical zoom and f/2 lens in an iconic design, creates interactive ―living pictures that can be endlessly refocused.
Lytro cameras feature a light field sensor that collects the color, intensity, and the direction of every light ray flowing into the camera, capturing a scene in four dimensions. To process this additional information, Lytro cameras contain a light field engine that allows camera owners to refocus pictures directly on the camera.

The Lytro camera is available in two models: 8GB ($399, 350 pictures, in Electric Blue or Graphite) and 16GB ($499, 750 pictures, in Red Hot). It is now available to order at and will ship in early 2012. The Lytro desktop application will be available initially for the Mac operating system;a Windows version will be available in 2012.
