Darkness
The Darkness function allows you to perform the exposure correction for the
current scan job. This function tries to average the intensity of the image and to
compensate for a very dark image, making the dark areas of the image much
brighter. However, a high darkness value will extend scanning processing time,
for it requires extra time to produce a better visible image. After each darkness
value, there comes a corresponded and suggested density value for your
reference.
To use the Darkness function,
1.
In the Preview window, click the "Overview" button to preview the image.
2.
Select the image area in the preview image where exposure will be applied.
3.
In the Settings window, click "Darkness", then choose a predefined setting
as you desire from its drop-down menu.
4.
Click the "Scan" button to start scanning.
