The Ranged Saturation tool controls the saturation of the shadows, midtones and highlights of an image.

Saturation: Includes controls for Shadow, Midtone and Highlight saturation.

Threshold: Determines the range affected by each corresponding Saturation control. Shadows are all values between 0.0 and the specified value. Midtones are the 'hump' of values between 0.0 and 1.0, centered on the Midtone value. Highlights are all values higher than the Highlight number.

Exposure Compensation: Corrects for any resulting changes in overall exposure.

Component Balance: Weights the operation to favor a particular color.
