Using the Color Cast Tool (LCH Mode Only)

The Color Cast tool is used to eliminate any

unwanted color casts in an image, as well as to

add a color cast without altering the lightness

channel “L” values.

In the example here, the original has a slight

cyan cast that makes the image look cold and

unappealing. The solution: Remove the

undesirable color cast.

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 preview from the

View menu.

4. Click the Color Cast tool in the Settings

window. The Color Cast screen will appear.

5. Move pointer toward preview image (notice

that the pointer turns into Neutral

Eyedropper pointer). With the Eyedropper

pointer, click the color cast that you wish to

remove. In the example here, we click on the

“watch tower” of the fishing boat to remove

the unwanted cyan cast.

6. 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

moments to show.

7. Click OK to confirm the correction.
