Everybody hates when they can't get their digital camera to focus properly. So researchers at Cornell University are hoping to change that -- by making it possible to focus photos after they're taken.

Cornell engineers are building image sensors that give detailed readouts of not only the intensity, but also the incident angle of light as it strikes the sensor. The result could be a new generation of 3-D cameras that allow the photographer to focus their pics later.

If you're like me and take the worst pictures, this comes as very good news.  Now you won't have to explain to everyone what every picture is.
