-Processes oversaturated colors to preserve hues. When one color component
-exceeds 1.0, the overflow is distributed to the other components, scaling the
-color towards white.
+Maps high dynamic range colors to 8-bit and applies gamma correction.
+
+An exponential curve (with exponent less than or equal to 1) is applied to
+simulate the response of the human eye. If the maximum color component of the
+result exceeds 1, the overflow is distributed to the other components to
+increase the apparent brightness without changing the hue.
