Example: Using the Desaturate Highlights Filter
In this example, the use of the Color Corrector filter to bring color detail out of the
blues of a diving clip has resulted in some unwanted reds in the bright highlights of
the image. To eliminate these unwanted reds without losing the other colors of the
diver and the background, you’ll use the Desaturate Highlights filter.
