Imagine light represented as a floating point number of the type a * 2 ^ b Stops describes the range of the exponent b. With a typical cinema camera, max_b > min_b + 14 You can use tricks like gradient ND filters to increase the perceived range within of a frame or variable NDs to slowly adjust over time (like our eyes do)
