Thanks to a Facebook post by photographer/model Lisa Bettany here’s info on a camera that takes a photo where you can change the focus after you’ve shot the image!
The camera is called the Red Hot from Lytro and it is what is called a light field camera. You have to read the claims and see the images to believe it. For example, in the photo on the right you can change which monk is in focus right in your computer.
It’s pretty neat.
