Use custom actions/tools
In order to streamline my workflow, I use actions that I have programmed and then bind them to keys on my Wacom or keyboard. In the video (at the 7:89min mark or vid 1) I use an action that creates a bunch of layers and adjustment layers that are all clipped and put in a group ready to be renamed properly. They are clipped in three categories: 1- The adjustment layers that I normally use: Curves, Hue/ Saturation, Color Balance, and Brightness/contrast. 2- Hue/saturation adjustment layers with masks generated by the automatic colour range selections of Highlights/midtones/shadows. 3- Copies of RGB channels that are pasted into masks. I use these different layers/masks
interchangeably to get the desired effect and often either delete the rest of the unwanted layers, or merge everything within the group. This tutorial should include the actions file.
I also use the custom tools such as an oval soft brush set to Color Dodge and Burn to help me with extracting masks (further explored in the next step).
