      Effect:Posterization
      Category:Special Effects
      Speed:Fast

      Description: The Posterization Effect reduces the number of colors in Color 1 and/or Color 2. Posterization is a popular photographic effect.

      Using Posterization on a solid color will produce little change. Posterization depends on having a varied Effect before it... a Texture, or some Procedural Effect, etc.

       
      Options: The Posterization Effect has the following Options Pane:

      % Color 1 ChangeThis value sets the amount of posterization applied to Color 1. The higher the value the more posterization is applied.
      % Color 2 ChangeThis value sets the amount of posterization applied to Color 2. The higher the value the more posterization is applied.
      Output Color 1:By default this is set to REPLACE which means that the set color will be output to Color 1. You can change this as explained in Options Pane Color Mixers.
      Output Color 2:By default this is set to IGNORE which means that the Color 2 will be ignored (the original Color 2 will be kept). You can change this as explained in Options Pane Color Mixers.

      Example: The following image combines two Effects. In Slot 1 we have the Texture Effect with our Arches National Park photo loaded as the Texture. In Slot 2 we have the Posterization Effect with % Color 1 Change set to 98. We have applied the Posterization only to the right half of the image so you can compare the differences:

      The following image also combines two Effects. In Slot 1 we have the 4-Color Gradient Effect with default values. In Slot 2 we have the Posterization Effect with % Color 1 Change set to 80. We have applied the Posterization only to the right half of the image so you can compare the differences:
