Luminance

Caption

Examples of high dynamic range luminance in views of a cave opening, where combinations of indoor and outdoor luminance can exceed a 10,000-to-1 maximum-to-minimum luminance ratio. The scene at the right is a blended image across multiple exposures, illustrating the human ability to see multiple targets (three uniforms and one car) across vast luminance differences in the same view.
