Have you ever taken a picture that would have been great if only it were in
focus? Of course you have. So have we, countless times. But those days
may soon be past all of us with the introduction of Lytro, an entirely new
kind of camera that allows users to completely change the focus of a
picture after the shutter clicks. And, according to AllThingsD, this next-
generation camera will be available before the end of the year.
The secret behind the Lytro camera is a new type of sensor that gathers
much more information about the light coming into the camera than the
sensors found on all other types of digital cameras. Rather than record a
finite amount of information about the light in a photograph, as is the case
with other camera sensors, the Lytro sensor records the entire âlight field,â
which is made up of âall the light rays in a scene,â according to the Lytro
website. This includes the color, intensity and direction of the rays of light.
Other cameras simply record all the light as a single amount of light.
