To create a Turing pattern in Photoshop, you start with a grayscale noise image and repeatedly apply a fixed sequence of filters: Gaussian Blur, Threshold, and High Pass. This iterative process is automated using a recorded Action bound to the F2 key.
Conditions: Start from a grayscale noise image.; Convert the layer to a Smart Object so filters remain editable.; Record the filter sequence as an Action.; Repeat the recorded filter sequence until a maze-like pattern emerges.

The Threshold adjustment converts the grayscale image into a binary (black and white) image by setting all pixels below a certain level to black and all pixels above to white. This step discretizes the continuous values resulting from the high-pass filter into the final distinct black and white pattern, acting as a non-linear operation akin to a bistable chemical system.
Conditions: Level is set to 127.; Applied after the High Pass filter.
