ADJUSTING THE IMAGE WITH THE SCAN MANAGER 23
BRIGHTNESS AND CONTRAST
Sometimes an item is scanned with the brightness and contrast set to be
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.
Dark/Light slider—adjusts the brightness of the scan. Drag the
slider to the right or left to increase or decrease the brightness.
Low/High slider—adjusts the contrast. Drag the slider to the
right or left to increase or decrease the contrast.
ADJUSTING THE OUTPUT SIZE
The output size is the width and height of the image after it is scanned.
For example, if you plan to print the image on a piece of paper you can
select the output size to be 8.5 by 11.0 inches.
