Focused Light Field

A focused light field is a way of capturing and manipulating light to represent 3D scenes with depth and perspective. Unlike traditional images, which only record color and brightness, a light field captures the direction and intensity of light rays entering a camera. When focused, this data allows you to digitally adjust the focus point after capturing the image, creating images that can be viewed from different depths or perspectives. Essentially, it provides detailed 3D information about a scene, enabling enhanced post-processing like refocusing or changing the viewpoint, much like looking through a window with adjustable focus.
