Lytro camera

A digital camera from Lytro, Inc., Mountain View, CA ( that enables the picture to be focused after it is taken. Rather than recording light as single amounts, the camera's microlens captures the entire light field, which is the color, intensity and direction of all the light rays. Instead of megapixels, the Lytro camera is rated at 11 megarays.

With shipments beginning in early 2012, the Lytro is the first commercial product of the light field technology, which required supercomputers to process the images in the past.

Point and Shoot
The Lytro is a quick point and shoot, because there is no need to focus the camera. In fact, there is no focus.

After the Fact
Using software in the camera or computer, the focal plane of the image can be selected at any time. (Images courtesy of Eric Cheng, Director of Photography,
