Chapter 3: Correcting Images in the RGB Color Space 3-13
Correcting Colors
The checkbox in the Color Correction section of the RGB Control window toggles
selective color on or off. The default mode is On.
Note: The Color Correction checkbox should
always be checked.
The sliders in the Color Correction section allow you to perform color correction
in the three separate color channels. To do so, proceed as follows:
1. Select the hue to adjust by clicking on the color wheel.
2. Click on the radio button of the desired color.
Note: Steps 1 and 2 above can be combined by
selecting a point in the image, which automati-
cally selects the proper hue and color.
3. Adjust the sliders to add or remove color(s) in a channel. Remember that
small movements in either direction can have strong effects.
Note: The boxes in each slider show arbitrary
reference numbers for your convenience. The
numbers to the right of the boxes show the RGB
values after the change.
4. Click on the Manual Update button in the window to check the results of
each change (or turn on automatic updating by clicking on the Auto Update
On button located in the Preferences Window).
The Before and After sections of the Probe provide real-time feedback for your
changes.
