We talked about Lytro few months back. Lytro is a step up in digital photography, redefining the way we shoot our photos.
With Lytro, you will always shoot 3D photos that are in-focus, no matter what. Instead of capturing a photo, it captures the complete light field – information that can later let you see the photo with any focus. Light field is mathematically all light rays in the vision. These light rays are captured as-is and later be used to show almost anything in the picture in-focus.

You can re-focus the image after taking it. The photos taken are also 3d, you still get that parallax feel to it. Also, the Aperture is wide open, and the photo is always bright, even under low light conditions. (All photos are taken with f/2, without losing the aperture.)
The photography is going to shift to all new level starting at price of $300.
