Light-field photography (also known as plenoptic photography) is an imaging technology that makes it possible to adjust the focus in an existing picture. Unlike conventional images, any area in an image taken with a light-field camera can be brought into focus to make a particular feature sharper or
I describe the design, prototyping and performance of a digital camera that records this light field in a single photographic exposure. The basic idea is to use an array of microlenses in front of the photosensor in a regular digital camera. The main price behind this new kind of photography is the sacrifice of some image resolution to collect directional ray information. However, it is

Lytro light field camera refocuses the future of photography
Digital light field photography frees us of this chore by providing the capability of refocusing photographs after exposure (Figure . ). The solution is to imagine a camera with the depth of the
Recording the light traveling along ray bundles inside the camera (the light field) enables computation of photographs with reduced lens aberrations. Simulated results are presented for …
Digital photography has made possible to quickly and easily it take a pair of images of low-light environments: one with flash to capture detail and one without flash to capture ambient illumina-
Digital light field photography consists of recording the radiance along all rays (the 4D light field) flowing into the image plane inside the camera, and using the computer to control the final convergence of rays in final images.

The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by the radiance.
And, sure enough, here is the Lytro Light Field Camera. There was a lot of excitement when the New York Times wrote about a small company promising to make focus errors a thing of the past. A camera that allowed you to focus after you take the picture.

Conventional photography obtains a sharp image of objects within a given ‘depth of field’; objects not within the depth of field are out of focus. In recent years, digital photography revolutionized the way pictures are taken, edited, and stored. However, digital photography does not result in a deeper depth of field or better focusing.
