Bleach blending

The Bleach blending belongs to the inverter blendings. The result image looks as if one or both or the source images has been inverted.

The Bleach blending calculates the following simple formula for each pixel of each color channel:

CR = 1-(1-CB)*(1-CT) (Note: why this is the same formula as Screen Blending? Please correct.)

where CR is the intensity of the color channel in the blending result within 0..1 range.

CB is the intensity of the color channel in the bottom image within 0..1 range.

CT is the intensity of the color channel in the top image within 0..1 range.

No parameter belongs to this effect.

The Bleach blending is used to create photo negative style blends.
