in the image itself). The monitor gamma setting allows
you to change the gamma values for your monitor.
The monitor gamma only affects the prescanned
image in the prescan area. This is because image-
editing applications have their own monitor gamma
settings. The settings defined here should be exactly
the same as the settings in the image-editing
application you will use to view and edit the scanned
image.
There are different situations that might affect
your ability to correctly view images: Lighting
conditions, human perception of colors, and the
monitor you are using are some common factors.
To correctly adjust the monitor gamma, you must
first have your computer and working environment
stable. This includes the lighting in the room, and
making sure your monitor brightness, contrast and
colors are properly adjusted. Next, drag the slider bars
to alter the monitor gamma. When finished, click OK
to exit.

correspond to the monitor gamma values in your
image-editing/graphics program. This ensures that
