Weihai-Morning rain to provide the material map: Oh, I'm sorry Weihai-morning rain ha, if not clear words, is my wrong.

This case is mainly done by using the channel panel and the "Deepen tool" to remove the shiny skin from the person's face. Set the color mode of the image to CMYK mode, then compare the image effects of each channel in the channel panel, then use the "burn tool" to smear the shiny part of the character's face, and finally use the "Fix brush" tool to decorate the face color.
1. Open the material map and convert to CMYK mode.
2. Copy layers. Enter the channel panel.Classification:
