The result will be a visible boost in image saturation, but in a subtly different way then
were you to simply raise the Saturation parameter. Experiment with different images to
see how this works.
Note: The total value of 48 that’s used to add to (+48) and subtract from (-24, -24) each color channel
combination is arbitrary, the important thing is to balance the amount you’re adding with the two half-
values you’re subtracting.
Example 2: Patching Clipped Color Channels
In this second example, you’ll see how you can limit the effects of the RGB Mixer to selectively “patch”
portions of an image with unwanted clipping in one of the color channels. In the following image, the
red channel of the highlights was clipped during the shoot, and the subsequent rebalancing of the
highlights has only lowered the flattened top of the red channel as seen in the RGB Parade scope to the
right of the image. The result is a subtly harsh, flat region that is unflattering.
The original image on the left, and the altered version on the right.
At top, the original image. At bottom, the result of an RGB Mixer adjustment with “With luminance level preserved”
turned on. You can see that lowering the green channel slider also raises red and blue.
