In this video, I show you how to understand mask calculations in DxO PhotoLab: addition, subtraction, intersection, shape inversion, mask inversion, submask calculation order, and bottom-up reading logic. DxO PhotoLab's local corrections are very powerful, but their logic can quickly become confusing. You create a main mask, add submasks, invert a shape, invert a mask, sometimes use a control line… and the result isn't always what you expected. In this demonstration, I break down the logic of masks directly on a real image, using reverse engineering, to understand what PhotoLab actually calculates.
