THE TWO TWAIN INTERFACE OPTIONS 75

ADJUSTING GAMMA, SATURATION, AND COLOR HUE

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.
