The White & Black Points tool is used to change the
shadow and highlight points of an image. (See note on next
page for additional descriptions.)
By using this tool, you can manipulate an image to either
bring out the highlights in a very dark image, or bring out
more of the shadows in a very light image.
The White & Black Points tool can also be used to
neutralize the color cast in the highlight and shadow
regions.
In the example here, we need to set the shadows and
highlights, as well as correct the color cast on both highlight
and shadow regions.
1. Place the image to be corrected on your scanner.
2. Click the Overview button, and you will see the image
appear in your Preview window.
3. Select the area to be prescanned with the Scan Frame
tool, then click the Prescan button to obtain a prescan
image, and switch to the Prescan view in the View menu.
4. Click the White & Black Points tool in the Settings
window. The White & Black Points dialog box will
appear.
5. Check the Shadows and Highlights Auto Neutralize
options to “On” (default). This helps to neutralize the
color cast in the shadow and highlight areas of the
image.
6. Click the Auto button. This will automatically set the
optimal highlight and shadow points for the image.
7. Check the Preview box so that the image in the Preview
window is updated with the latest image correction. The
update is done in the background and so may take a few
seconds to show.
8. Click OK to confirm the correction.
