The Lytro is an incredible leap in photography innovation. By capturing the direction of light, it allows the photographer to focus the image on a variety of focal points after the shot is taken, allowing the viewer explore the scene in 3D.
When you shoot with any regular camera or phone, a blurry photo is generally incurable, as the 2D sensor simply records the image coming through the lens. In contrast, the Lytro records both the intensity and angle from which the light arrives, meaning the camera can reconstruct various portions of the photo in sharp focus.
For creative photographers, the Lytro gives unprecedented depth to whatever you point it at. It is also perfectly compact, weighing only 7.6 ounces and measuring 4.4 inches long.
