Highlight
This control changes the highlighting of the entire image. It sets the value
that the scanner and/or your image processing software uses for the white
reference. Increasing the highlight value darkens the light areas of your
image. Decreasing the highlight value lightens the light areas of your image.
The Highlight value represents the lightest value in an image. All pixels
above this point will be rendered as pure white. If you subsequently broaden
the highlight 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 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.
