Focus it Right !!

Yes its true. Lytro the new technology in photography lets you to change the focus after picture is taken.

The breakthrough is a different type of sensor that captures what are known as light fields — basically, all the light that is moving in all directions in the view of the camera. It gives capabilities you never had in any conventional cameras.

So wondering how it works. Light travels everywhere instead capturing only single plane of light, Lytro captures the light field travelling in every direction at that point . Like every eye sees it normally.

This technology free the use of auto-focus motor as focusing after the image is taken.
