[. . . ] 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. In the example here, the original image is underexposed, with the middle tones of the image being too dark. Click the Overview button, and you will see the image appear in your Preview window. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. The Gradation screen will appear. Image corrected with Gradation tool Original image 5. Move the pointer over the curve, and drag the center of the curve to the left.
