Use the Advanced Settings tab to set color correction options for Color or Grayscale scanning. Drag the sliders
to the left and right to change the color settings. As you do, the image changes to show the effects of the
new settings.
• Color saturation —the strength or purity of a color. This option is only available when the selected
scan mode is Color.
• Color hue —the color your eyes see as reflected from the image. This option is only available when
the selected scan mode is Color.
• Gamma —is the tone curve and the starting point for image enhancement. As you raise or lower the
Gamma value, the values at which saturation, hue, brightness and contrast affect the image are
changed. It is recommended that you keep the default Gamma value or adjust this setting before
adjusting the other options. This option is available for both Color and Grayscale scanning.
