The lightfield camera is a computational camera that achieves imaging of object at multiple depths with single exposure. Instead of recording total intensity at each pixel as in usual camera, the lightfield camera system keeps track of directional distribution of light at each pixel. This information enables us to perform computational refocusing. The commercial product has been recently introduced by Lytro systems. We have studied working related to the computational photography and after this we have developed some code in matalab for recording the intensity pattern at detector and also developed code for image recovery. Finally we did experimental work and recorded the Light field and then applied image recovery algorithm. After this we got the photograph of an object at different depth from the single recoded pattern at a particular location.
