Using Channel Mixer to Adjust Color Cast Photo Tutorial

Original picture

final renderings
The idea is that since both the green channel and the red channel are damaged, use the channel mixer to repair them, then use color balance to make fine adjustments, use optional colors to make subtle skin tone adjustments, and finally perform a certain degree of skin resurfacing and brightening.
I have simply summarized the process as follows. I hope it will be helpful to everyone in the process of correcting color casts.

1. Use the channel mixer to repair the channel.

2. Use color balance to adjust to remove the reddish color.

3. Use optional colors to adjust skin tone.

Fourth, use color levels to improve, basically completing the adjustment of the color shift of the original image, and the rest is local modification.

5. Finally, through local trimming and increasing saturation and contrast, a certain degree of skin resurfacing is performed, and finally the rendering is obtained.
