      Effect:Color Dodge
      Category:Math and Logic
      Speed:Fast

      Description: The Color Dodge Effect produces a traditional photographic Dodge effect.

      The Color Dodge Effect divides Color 1 by an inverted Color 2. This lightens Color 1 depending on what's in Color 2. The brighter Color 2 is, the more its color affects Color 1. Dodging with white gives white. Dodging with black does not change the image. When Color 2 is homogeneous, this effect is equivalent to changing the white point to the inverted Color 2.

       
      Options: The Color Dodge Effect has the following Options Pane:

      Dodge Red:If set to a Red X, the Red Channel is not Dodged. If set to a Green Check Mark the Red Channel of Color 2 is Dodged to the Red Channel of Color 1.
      Dodge Green:If set to a Red X, the Green Channel is not Dodged. If set to a Green Check Mark the Green Channel of Color 2 is Dodged to the Green Channel of Color 1.
      Dodge Blue:If set to a Red X, the Blue Channel is not Dodged. If set to a Green Check Mark the Blue Channel of Color 2 is Dodged to the Blue Channel of Color 1.
      Dodge Alpha:If set to a Red X, the Alpha Channel is not Dodged. If set to a Green Check Mark the Alpha Channel of Color 2 is Dodged to the Alpha Channel of Color 1.
      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 images show the Color Dodge Effect.

      In this example we combine three Effects. In Slot 1 we have a Texture Effect with our Arches National Park photo loaded. In Slot 2 we have a 2-Color Gradient with the top color set to black and the bottom color set to white and Output Color 1 set to Ignore and Output Color 2 set to Replace:

      In Slot 3 we place our Color Dodge with default values. This is the result:
