The Desaturate Highlights and Desaturate Lows Filters
Sometimes, the use of the Color Corrector filter results in unwanted colors appearing
in either the highlights or shadows of your image. The Desaturate Highlights and
Desaturate Lows filters allow you to target a range of the brightest and darkest areas of
your image and desaturate them, which helps to keep the highlights and shadows of
your image free from coloration.
The Desaturate Highlights and Desaturate Lows filters are actually the same filter, but
with different default settings. If you need to desaturate the highlights and the
shadows, you can apply either filter once and then select both options.
