Image Posterization

The Posterize adjustment creates a simpler image by reducing the number of lightness levels in each color channel. Watch our video tutorial to learn more about the Posterize adjustment.

Select Image -> Adjustment -> Posterize... to make the adjustment parameters appear in the Settings Panel.

You can also use a Posterize adjustment layer (Layers -> New -> Adjustment Layer -> Posterize...) which will affect all underlying layers without changing their content.
