Lytro is seeking to revolutionize photography. It's introducing a true point-and-shoot camera that takes living pictures.

These pictures can be refocused later - by both the photographer and viewer. It can also switch seamlessly between 2D and 3D views and allow for better pictures in low light conditions.

The concept/technology behind this camera is light fields, or light traveling in every direction that permeates a space.

The light field sensor captures the color, intensity and vector direction of the rays of light. This directional information is completely lost with traditional camera sensors, which simply add up all the light rays and record them as a single amount of light, said the company.

Below are sample living photos from Lytro. To change the focus, simply click on different spots on the pictures.
