During installation you will see this window asking you to select an
image for your Color Space setting.
The Color Space setting sets the gamma value for the scanner so
scanned items look good on your monitor. Gamma controls the
brightness of the midtones of colors. That setting can be changed
later on as you’re scanning.
Note: If you decide to change the scanner’s installed drivers later on,
you must first uninstall the drivers the scanner is currently using. See
the instructions on page 120.
