Unfortunately, many of my digital images end up looking more like this picture than I'd like to admit, so it was with a happy heart that I read about a new technology that could refocus photos after they've been taken. A team at Stanford University are claiming to have figured out how to adjust the rays of light after they've reached the camera, thereby letting us make blurry, nasty images look good as new. To do this, they inserted a sheet of 90,000 lenses between a cameras main lens and its image sensor. The angle and the amount of the rays of light are then recorded, letting software adjust them, basically reconstructing the image to what it would have looked like if properly focused. Not a bad deal. Now how can we convince the camera manufacturers to get on board?
