Cramming more and more megapixels into digital cameras is so last-decade. The latest innovation in the world of photography is Lytro's upcoming light field camera, which lets users focus a picture after it's been taken. In a demonstration at Brainstorm Tech, founder and CEO Ren Ng shows how it works: A tiny sensor records more light beams than conventional cameras. The extra information, saved in each image file, allows photographers to tweak their shot long after the "Kodak moment" has passed. The company says it will come out with a "competitively priced" camera for the consumer later this year. Who'll buy one? Perhaps Starbucks CIO Stephen Gillett, who, after seeing Ng's demo, tweeted, "New Lytro camera is so disruptive it is going to cause major 'innovator's dilemma' headaches for camera companies."
