A professor from my university bought a Lytro light field camera. We played around with it for a while. Although the Lytro’s form factor is different, you take pictures with it just like you would with your average digital camera. Simply push down the release button and you take a picture. The camera stores the pictures on its internal memory and you have to hook up the Lytro to your computer to download the pictures using the Lytro software. As the camera uses a proprietary format to store the pictures, you have to use the Lytro software to watch them.
