DJUSTING AMMA ATURATION
If you're using the Color Configuration to scan, you can adjust a group of color
settings. Gamma controls the brightness of the color midtones. Saturation is
the strength or purity of a color and hue is the color your eyes see as reflected
from the image.
The following figure shows the color options.
To adjust the color settings:
1. Drag the Gamma, Saturation, and Color Hue sliders to the left to
decrease the settings or to the right to increase the settings.
You can also type a number directly into the setting boxes, or click the up
and down arrows next to the boxes.
The Gamma setting is available when scanning Grayscale.
2. Click Reset to return the settings to their original numbers.
