Math actually place a big role in the film industry! In every computer-generated model, math has a key role. Every model uses explicit math representations as a meshed surface or volume. Polygons are especially used to create the surface of any 3d model. The F-stop is a measurement of light coming through the lens into the sensor. It decides the brightness of the footage! Histogram is a pixel map that shows how dark and light pixels are distributed within the footage.
