provides Midtone adjustment for you to compensate for these
differences in your scanner, and it produces better scanned images.
To change the Midtone value, move the Slider to the left or right to
change the values in the adjacent text box. The value in the
adjacent box will change in the range 0.10 to 10.00 as the slider
moves.
Ordinarily, good results can be obtained from your machine by
leaving the slider at its default value of 1.50 for Gray and 1.30 for
Red, Green, and Blue.
You may select the Reset Settings from the Settings menu to get
the default value. However, you can adjust the tone values of any
or all of the color channels of your images by selecting the Red,
Green, or Blue Channel buttons and dragging the sliders to
change the Midtone value. You can also directly enter a value in
the textbox.
The Advanced Selection
The Advanced selection will present features that allow you to
modify the Level Adjustment and Tonal Map of the document.
For both the Level Adjustment and the Tonal Map functions, the
window displayed contains small representations, known as
thumbnail views, of the original and enhanced images (Samples 1
and 2).
