Usually when we take the snap we can either focus Foreground or Background. As seen in the image below.(Image Courtesy to Lytro company)
So Lytro company has invented new Technology, in which any one who like's Photography or just want to click the photo will have capability to focus images after the snap has been taken.
Just Click were ever you want to focus and the image changes it's Focus.
Lytro is transforming the camera into a powerful computational photography platform and making conventional cameras a thing of the past. The key innovation is “light field” technology, which captures all of the light rays in a scene to create interactive, living pictures. Light field innovation enables unprecedented capabilities, including the ability to focus after a picture is taken, remarkable low-light sensitivity, and 3D viewing.
The company was founded in 2006 by CEO Dr. Ren Ng, whose research in light field photography won best PhD dissertation in computer science at Stanford in 2006 as well as the internationally recognized ACM award.
The light field is a core concept in imaging science that has been extensively researched for more than a century in academic environments.
Until recently, light field cameras involved a roomful of hundreds of cameras tethered to a series of computers in a lab. Dr. Ng has dedicated more than six years to researching this science to bring the technology out of the lab and make it available for everyone.
For a deeper look at the technology, see the Lytro site and Dr.Ng’s research.(this is the .pdf)
Light field cameras are revolutionary in that they capture the entire light field, unleashing capabilities that were never before possible, including focusing a picture after it’s taken. Lytro cameras will allow users to experience amazing capabilities including:
Shoot now, focus later. People will no longer be delayed by having to focus their camera or be disappointed when a picture turns out irreparably out-of-focus.
Lytro pictures can be flawlessly focused to their liking – days, weeks, even years after they’re taken.
Unparalleled speed: Since the camera doesn’t focus before a photo is taken, people will no longer miss important moments due to autofocus shutter lag.
Living pictures. Lytro creates pictures that both the photographer and viewer can interact with when shared online on blogs, photo sharing sites, their favorite social media networks, etc. They can focus the foreground, background or the entire image simply by clicking on an area of detail. No software download is required.
Low-light sensitivity. By using all of the available light in a scene, light field cameras can capture better pictures in remarkably low light environments without use of a flash.
Immersive 3D. Using the full light field, Lytro cameras will allow people to easily switch
between 2D and 3D views or shift the perspective of the scene.
The team at Lytro is completing the job of a century’s worth of theory and exploration about light fields. Lytro’s engineers and scientists have taken light fields out of the lab miniaturizing a roomful of cameras tethered to a supercomputer and making it fit in your pocket.

Light Field Technology
The light field is a core concept in imaging science that has been extensively researched for more than a century in academic environments.
The light field is defined as all of the light traveling in every direction through a scene, from the foreground to the background and everything in between.
