Lytro lets you take pictures like never before. 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.
Capture living pictures with the press of a single button. By instantly capturing complete light field data, the Lytro camera gives you capabilities you've never had in a regular camera.
Focus after the fact.
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 any time.
And focusing after the fact, means no auto-focus motor. No auto-focus motor means no shutter delay. So, capture the moment you meant to capture not the one a shutter-delayed camera captured for you.
Lytro camera image is a 3D map of whatever was photographed, and that means people can literally decide what to focus on after they've taken the photo.
On the outside, the Lytro looks different--a smooth, two-tone elongated box 4.4 inches long and 1.6 inches square. At one end is the lens and at the other is an LCD touch-screen display; along the sides are power and shutter buttons, a USB port, and a touch-sensitive strip to move the F2 lens through its 8X zoom range and 18MP.
Camera is available for on-line shop in 3 colour versions, Red Hot, Graphite and Electric Blue in two memory versions 16GB and 8GB.
