Pocket-Sized Light Field Camera Takes Photos You Can Refocus Later
Lytro creates interactive "living pictures" that capture all the rays of light in a scene.
This week, the small but mighty Lytro camera was unveiled, which captures interactive photographs that can be shared and refocused online. The pocket-sized camera packs a powerful 8x optical zoom and f/2 lens, and its innovative light field sensor captures 11 million light rays of data, including the direction of each ray. The light field engine it contains then processes the data into an HD quality picture. This can be refocused on the camera, and when the photographs are shared online, the light field engine travels with them so others can interact with them on mobile devices, without the need for specialist software.
