The Selective Color tool is used to perform color
correction to a specific color range without altering
the other colors in an image. This is done either to
increase the visual impact of a color or to completely
change the relationship of the targeted color(s) to the
other colors in the image.
In the example here, we want to increase the
saturation of the sky and change the boat color but
leave everything else untouched.
1. Place the image to be corrected on your scanner.
2. Click the Overview button to see the Overview
image 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 Selective Color tool in the Settings
window. The Selective Color screen will appear.
5. Select the "From" color or the color to be
corrected. In the example, move the pointer over
the blue sky in the Preview window, then click on
the blue sky. (Steps 5 to 9 are repeated for the
change in the ship's color. Click the New button to
define a second color.)
6. Check the Show Affected Areas option to see the
targeted color(s).
7. Adjust the color range to be affected (the LCH
values). To do this, drag the arc of the color wheel
and the sliders of the lightness bar until only the
sky's blue color is affected.
8. Enter the "To" color or the color that will take the
place of the original. Enable the "To" color mode
by clicking on the "To" color label prior to
entering the color. In the Color Wheel, move the
"To" color marker to the desired chroma position.
9. Uncheck the Show Affected Areas option to see the
corrected result, displayed on the right thumbnail.
