The idea is that rather than focus the shot and then take a picture, the picture taken with a Lytro holds all the information needed to focus the image at any given point in post-processing. I think. So no more blurry shots?! Which could prove very handy as I have some lovely photos I took which looked fine at the time on the camera but turned out to be a little out of focus once I put them on the PC. Still, some new technology from Adobe .
