ZDNet’s technology blog has an article about a new camera, dubbed the “light field camera”, that allows you to change the point of focus AFTER a photograph has been taken. You can already change the exposure, white balance etc on today’s digital cameras (especially if you use the RAW file format) - the cameras of tomorrow could allow you to decide what you want to be in focus in the comfort of your own home.

“By inserting a microlens array between the main lens and the photosensor, their “light field camera” takes one shot, but also captures information about light conditions. And you can later compute “photographs in which subjects at every depth appear in finely tuned focus.” However, his new technology will probably appear for applications such as security surveillance and commercial photography before landing in your personal camera.”
