TONE CURVES
The Tone Curves dialog box displays curves for the prescanned image inside the cropping frame. The curve
represents the input brightness values (x-axis) in relation to the output values (y-axis). This dialog box allows you to
make changes to the tone curves. It is possible to make changes to the individual curves for each channel; red (R),
green (G), and blue (B), or to make changes to the overall curve (RGB curve).
Click on in the Prescan window to
open the Tone Curves dialog box.
