You can edit the tone curve directly by changing the shape of the line on the
graph. When you change the setting by manipulating the curve, you can perform
fine adjustments in the brightness of only the shadows, only the highlights, or both
the shadows and highlights.
Hint
•You cannot use this feature with the black and white or color scan modes
when ColorSync is selected.
