the intensity of the colors of the image being scanned. You can
adjust the shadow, mid-tone, and highlight values, which helps

Use of the tone curve is recommended for fine adjustments after you
have previewed the image and adjusted the highlights and the
shadows using Auto Exposure and the Image Controls dialog box.
Use of the tone curve to make initial settings is not recommended.
