Highlight / Shadow
This feature is available when 8-Bit Gray, 8-Bit Color, or 24-Bit Color
is selected on the
Image Type drop-down menu. Highlight refers to
the lightest point in a scanned image; shadow refers to the darkest
point.

the text boxes or you can place the mouse cursor over the

Use the Highlight and Shadow settings together to extend the range
of color and reveal more detail in a color image.
Curves
When you select the Curves button, a dialog box appears
that allows you to adjust the midtone of the image without
losing detail in the lightest and darkest areas.
Select the Curve or Line button, depending on whether you want a
curved or an angled setting. Place the mouse cursor over the line, click
the right mouse button, and drag the line to set the curve you want.
