London, Oct 21 (ANI): A revolutionary digital camera that allows photographers to focus their pictures after taking them has gone on sale.
Lytro, which looks nothing like a conventional camera, captures data about the intensity and direction of all the light entering the lenses rather than recording a single version of an image.
The information taken can be reorganised later with the option of changing which parts are blurred and which are sharp.
The "light field" technology, which was developed by company founder Ren Ng while he was at Stanford University, is in some ways analogous to the practice of shooting RAW images with a current generation digital camera.
The device records all of the light falling on its sensor without running it through processes such as colour balancing or sharpening and these can be applied later on a computer.
Similarly, by recording the light field passing through many tiny micro-lenses in the Lytro, the action of merging these to create a single flat image can be applied as a post-production effect.
"Light field photography was once only possible with 100 cameras tethered to a supercomputer in a lab," the BBC quoted Ng as saying.
According to the company, Lytro's image sensor is capable of capturing 11 megarays of data, whereas the feature of producing 3D images will be added at a later date. (ANI)
