Lytro has introduced its new light field camera, which lets you focus a picture AFTER it’s taken.

Not only is it pocket-sized and rectangular, it has an eight-times optical zoom and is available in three different colours.

The reason this little light field camera has received so much hype is the way it captures light rays. Lytro says the light field camera captures the rays of light using a light field sensor, which collects colour, intensity and the direction of the light rays.

The camera also contains a light field engine to allow users to refocus pictures directly on the camera – after the picture has been taken.

The best part is the lack of need for a flash to take pics in low-light environments – no more unflattering dazzle shots.

The Lytro camera offers two storage models of 8GB and 16GB, starting at $399 and shipping in 2012.

The desktop application will only be available for Apple Mac operating system until a Windows version is released at a later date.
