Photographic Contrast Masks Using Cellular Automata

Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
Contrast masks are commonly used to adjust the tone of specific areas of a photograph. The mask in this Demonstration is generated by a two-dimensional cellular automaton using a binarized version of the photograph as initial condition.
