Using AIC Tools 4-11 English English Using the Gradation Tool (LCH Mode only) The Gradation tool lets you adjust the midtones (the mid-level grays) of the lightness channel "L" of an image without altering the color itself. This is because even with changes to the luminance or lightness value, the chroma and hue values are kept constant. To prevent color images from losing saturation when adjusting the lightness, ScanWizard Pro provides a Saturation Range option. With this option, colors outside of a given chroma range are not affected by the manipulation of the gradation curve.
