Channel Swapper is available in the Color: Looks Pack.
Replaces channels with other channels. For example, you can have a layer’s alpha (transparency) set to correspond to its red values, or its saturation. This is useful for both color grading and compositing. Channel swapping is also frequently used in Infrared (IR) photography.
