G a m m a

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

will save you time correcting the image later in an editing application.

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.

Image Information

Information about your pre-scanned image is displayed in boxes along

the bottom of your TWAIN window. Use this information as a guide

when determining what scan mode and resolution you want to scan

at.  The information as displayed from left to right is as follows:

•  Cursor Position Displays the coordinates of your cursor

position as it appears on the image.

•  Scan Area Coordinates  Displays the coordinates at which

the top left corner of the cropping box originates.

•  Scan Area Dimensions  Displays the dimensions of the image

in inches or centimeters.
