Abstract :
Lytro, a Silicon Valley start-up, has just launched the world´s first consumer light-field camera, which shoots pictures that can be focused long after they´re captured, either on the camera itself or online. Lytro promises no more blurry subjects, and no shutter lag waiting for the camera´s lens to focus. A software update to the camera, coming soon, will even let you produce 3-D images.
