It may not make sense to many but I totally dig the idea of a camera that allows you to focus at points you wouldn’t think of while clicking the images. Those who claim to have ghosts walking past their images will agree. The Lytro camera is pure awesome with the light-field camera technology in it. The magic is achieved by putting an array of micros lenses over the sensor. A lenticular array thus takes up the focal plane of the camera. Hence the camera records the direction of light along with the colors in the image as it uses more software than hardware that conventional shooters use. The camera also allows you to gain an enhanced view of the foreground objects in lenticular manner, enabling you to view behind the foreground objects.

This could pimp the way we click images. This could make post-shoot experiences more fun that the actual shooting itself.
