Groundbreaking camera lets you shoot now, focus later

This new camera technology  is going to revolutionise the way we take photos.  Spend the time to work through the photo examples and click on new photo areas. 

Lytro allows post-shot refocusing by taking advantage of something that conventional cameras cannot: the light field. The light field consists of all of the light rays in a scene, meaning every single light ray traveling in every direction through every point in space.

Scientists have fantasized about light-field cameras for a century, but previous experiments in creating one required the equivalent of 100 digital cameras connected to a supercomputer.

The Lytro takes that 100-digital-cameras-plus-supercomputer capability and stuffs it into a regular-sized point-and-shoot.

The company does this with an innovative sensor called a light field sensor. The light field sensor takes in three pieces of data about each ray of light: its color, intensity and direction. Conventional camera sensors just add up all the light rays and record them as one amount of light instead of recording information about each ray.
