Sometimes an item is scanned with the brightness and contrast set too
light or too dark. For example, a note written with a light pencil may
need to be scanned darker to improve legibility.
Brightness refers to the lightness or darkness of the image. Contrast is
the range between the darkest and lightest portions of the image. The
greater the contrast, the more the difference between the lighter and
darker shades in the image.
