The larger the pattern area, the more gray levels that can be represented, but with
a grainier result. Dither patterns can also be downloaded to achieve special
effects.
Shadow, Midtone, and Highlight
These sliders can be used to enhance the dynamic range of the images you scan.
If you have an image with lots of midtones that you would like to differentiate,
these controls can help. They allow you to specify the resolution of gray tones at
particular intensity levels, which in turn affects the overall brightness of the
image.
Shadow adjusts the level of the darkest dark for scanning. Below this value, all
pixels will be black.
Accordingly, Highlight allows you to bring down the top end of the range into
the midtones.
Midtone lets you set the intensity level corresponding to medium gray.
Scanner Reports
This is a small text display area that shows information about the scanner you are
using. Information here will include ROM version information and other
information that particular scanner models report about themselves.
