What if you could refocus pictures after the camera has taken them?
With the new Lytro camera, you can. With the Lytro, pictures are taken just like any other camera, but the digital files are much larger and can be refocused later. This is possible through the new technology introduced through the camera. Not only does the Lytro take into account the brightness of incoming light, but the direction the light is coming from and the colors it contains. Scientists call this information light-field data. With this technology, the camera can focus and refocus over again just by tapping the touch screen.
The camera is about the size of a stick of butter. The lens is on one side, and the small touch screen on the other. Unfortunately, the touch screen is too small and the quality is a little grainy. However, this technology is a big step away from traditional focusing implemented in modern cameras.
