Lytro Light Field Camera
So how would you like to have a digital camera where you could focus the image on your computer long after the picture was taken? That's exactly what happens with the Lytro Light Field Camera.
If you have shot RAW images with a DSLR, you already know about processing images in the computer later. While RAW files allow for all kinds of adjustments, they don't allow you to refocus on any part of the image you like. I don't expect that this camera will replace your DSLR, but it does give you something to complement it. This is definitely camera technology you'll want to follow.
