An Example of Color Curves in Use
In the following example, you’ll see how to make a targeted correction to eliminate a
color cast from the lower midtones, shadows, and extreme highlights of an image,
while actually strengthening the same color cast in the lower highlights.
The following image has a distinct red color cast from the shadows through the
highlights, as you can see by the elevated red waveform in the Parade scope.
Note: For clarity, Broadcast Safe has been disabled so you can better see the bottoms
of the waveforms in the Parade scope.
In this particular shot, you want to keep the red fill light on the woman’s face, as it was
intentionally part of the look of the scene. However, to deepen the shadows of the
scene and make the subject stand out a little more from the background, you’d like to
remove some of the red from the shadows.
1 Add a control point to the red curve near the bottom of the curve, and pull down until
the red color cast becomes subdued.
This should coincide with the bottom of the red waveform in the Parade scope lining
up with the bottoms of the green and blue waveforms.
