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.

You can choose different resolutions and a different binarizing threshold. Different rules generate a variety of mask patterns. Increasing the steps makes the mask grow in size.

The adjusted photograph is made by blending the original with the mask. Setting the blending fraction to 0 shows the original photograph. Setting the blending fraction to 1 shows the mask only.
