Scripting command: exposure [Amount=-100...100] [Mode=0...1]
Like exposing your camera sensor or film a different amount of time. You can select RGB or luma processing; RGB will result in nonlinear color changes when any R, G or B component reaches the maximum value, while luma processing avoids this, but does not increase the lower of the three channel components any further than the largest component allows when it hits the maximum in order to keep the hue of the image the same.
