The options of the Advanced Settings tab are for the Color or Grayscale
scanning modes.
Drag the sliders to the left or right to change the color settings. As you do, the
image changes to show the effects of the new settings.
■ Color Saturation—is the strength or purity of a color.
■ Hue—is the color your eyes see as reflected from the image.
■ Gamma—is the tone curve and the starting point for image enhancement.
As you raise or lower the Gamma value, the values at which Color
Saturation, Color 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.
On installation, the Color Space screen requests that you choose a flower
that looks good to you. The flower you choose is the default Gamma value
for the scanner.
Note: Color Saturation and Hue are only available when scanning in color.
Gamma is available for both color and grayscale scanning.
