The Highlight scroll bar allows you to manually set a highlight level. The
default for the Highlight settings is 255. You can increase or decrease the
highlights in a particular image as needed by adjusting this scroll bar. The
value in the adjacent box will change in the range 1 to 255 as the slider
moves.
Shadow
The Shadow value represents the darkest value in an image. All pixels
below this point will be rendered as pure black. If you subsequently broaden
the shadow points on the Level Adjustment graph, the pixels will be re-
mapped within the new range thus allowing you to see more detail in the
image.
The default value for Shadow is 0. You can increase or decrease the
shadows in a particular image as needed by adjusting this scroll bar.
Midtone
All optical devices such as monitors and scanners have some differences in
their light sensitivity characteristics. 385Scan provides Midtone adjustment
for you to compensate for these differences in your scanner, and it produces
6
better scanned images.
