1. A method of modifying saturation of an image, the method comprising: receiving an image including pixels, wherein each pixel comprises color components including a saturation component and a luminance component, wherein the color components of each pixel include an unilluminated color component of an illuminated entity included in a scene and an illuminated color component of the illuminated entity included in the scene; modifying at least a portion of the illuminated color component based on the unilluminated color component; determining a saturation gamma curve, wherein the saturation gamma curve is based on a function of a plurality of parameters, and wherein one parameter in the plurality of parameters comprises the luminance component; determining a saturation gamma mapping value based on the saturation gamma curve; and determining a modified saturation component based on a power function of the saturation component and a reciprocal of the saturation gamma mapping value.
