Today all the buzz in the photo world is coming from an unusual tech company called Lytro. A new camera called the Lytro Light Field Camera uses a groundbreaking new sensor design that allows more light to be recorded than normal sensor technologies. This in turns actually allows you to choose your focus point after you have taken the photo (click on any of the photos in this post). As of right now no major camera companies have picked up this technology for their own cameras, but worry not as Lytro is working on creating a small point and shoot camera that will feature this "focus later" sensor soon. Check out the example images below as well as some commentary from the Wall Street Journal. Do you guys think this is a good idea or a practical application of selective focusing?
