A “light field,” first of all, is the amount of light traveling in every direction, through every point in space. Regular digital cameras simply combine all the light rays, and represent them as one amount of light. Using a microlens array and a light field sensor, however, light field cameras record the color, intensity and vector direction of all the rays separately. Algorithms programmed into onboard software are then able to sort through all that data, and make it into one image. LEIA MAIS AQUI.
