Gamma refers to the numerical value for the level of intensity or brightness in the tones of color or grayscale images. As the number increases the tonal intensity increases. Your TWAIN interface allows you to make adjustments for two types of gamma settings. Image Gamma refers to the gamma values that directly affect the outcome of the scan and will be saved with the rest of your scanned image information. This differs from Monitor Gamma which defines how the tones in an image will be displayed on your monitor. Monitor Gamma can be adjusted in the Advanced menu located at the top of the TWAIN window.

If the color or tones in your Pre-scanned image are off balance, using the Gamma controls to make adjustments to the pre-scanned image willsaveyoutimecorrectingtheimagelaterinaneditingapplication. The Settings menu located above the preview window limits you to Gamma 1.0 or Gamma 1.5 for scanning color or grayscale images. However, The Image Gamma levels for each RGB channel can be balanced individually in the Enhance window (located under Advanced). These changes are effective immediately, and are shown in your pre-scanned image.
