Highlighting The Subject Using RGB Channels
Mastering the channel mixer allows you to not only adjust white balance, but also creatively color grade a photo to set the mood, change the luminosity, and make local adjustments to specific areas of the photo. In this example, we use color calibration to highlight a subject when the surrounding content, in this case the green foliage, is naturally brighter than the subject and thus pulls your focus away. We can counteract this using channel mixer in color calibration.
