If you are working with a color image, select the appropriate color channel.

Move the Contrast and Brightness sliders to the left for less contrast or brightness, and to

the right for more contrast or brightness, until the desired contrast is achieved.

The image in the preview area reflects your changes.

Changing Gamma Curve Values

With the Gamma curve, you can change the mid-tones of the image to increase its contrast, and

enhance the overall image. When you increase the Gamma value, light areas are made lighter,

and dark areas are made darker.

For example, if you are scanning a photograph that has many dark tones, simply adjusting the

brightness and contrast may not improve the image as effectively as adjusting the Gamma value.
