In the example below, the original has a slight color cast in the shadow and highlight portions of the image. With the use of the auto neutralizing and auto adjustment features, the color cast is removed, and the shadows and highlights are remapped accordingly. 3 4 NOTE: The shadow point is defined as the lightness value "L" in an image that is output as black (mapped to the Minimum Output Level), while the highlight point is defined as the lightness value "L" that is output as white (mapped to the Maximum Output Level). The default values of the Minimum Output Level and Maximum Output Level are L=5. 0 and L=95. 0, respectively. 6 5 7 Using the AIC Tools 4-11 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 TX 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.
