Lytro's Photo Magic Lets You Refocus After Taking a Picture
Technology is a never-ending aspect of science. More and more companies and people are contributing to technology.
A Silicon Valley Startup (Ren Ng from Stanford University founded) “Lytro”, makes one such contribution, in the form of a camera through which users can focus image after taking the photo.
The camera looks very similar to a telescope and has two buttons on it. One button is to turn the device on or off and the other button is to take photo. After taking the photo, user will have to focus the area or object on the resulting image with the help of touch screen on the device as everything in the photo is artistically blurred. However, the photo taken with this camera can also be set to show everything in sharp focus. Users can also feel the same experience with the help of Lytro’s software on PC or tools to embed images on Facebook or other websites.
More interesting is the “lightfield” sensor in the camera that makes it possible to see the photos in 3D. Pixels are more specialized to red, green and blue color in “lightfield” sensor and able to detect light coming only from a specific angle. Knowledge of angles of rays of light helps the camera to take photos according to different foci.
The photos taken with this camera are interactive and dynamic resulting in photography that is more creative and playful.
Lytro is a part of a comparatively young area of research known as Computational Photography.
