This Demonstration shows the effect of tone curve adjustments on an image. The tone curve defines the brightness relationship between the original input values (on the axis) and the resulting output values (on the axis). Adjust the tone curve by dragging the locators, choosing one of the preset schemes or changing the interpolation order.
