Lytro, a company you’ve probably never heard of, recently announced a camera that features a new approach to photography that you’re likely to be hearing a lot about in the next few years. Instead of producing a camera that packs more mega-pixels, or one that’s lighter or cheaper, Lytro has taken the initative to try and change the photography industry by making a camera that takes digital photos that contain enough information to allow them to be focused after they are taken... These data rich photos are taken using something called light field technology. In layman’s terms it works something like this. When you take a picture, light is reflecting off various surfaces in various directions. A standard camera takes a ‘shapshot’ of what it sees, recording the light that’s reflecting, but nothing about the direction. That gives you a standard photo. Light field pictures, however, also record information about the direction of the light, resulting in a picture that is more similar to a digital replica of the scene than a traditional ‘picture’ is. That is what lets you refocus.
