Ambient Light Compensation.
The Purpose of This Step
Your visual perception of an image displayed on a monitor is influenced by the
ambient (surrounding) light in the viewing area. Perception of tone may change as the
amount of light in the room increases and decreases. The best procedure is to keep

critical work.
If you choose to turn Ambient Light Compensation On then the program will measure
your surrounding room light and suggest any appropriate changes to your calibration
target values and/or ambient light conditions.
