Working With Photoshop Masks and Channels
Select and Mask, Quick Masks, Puppet Warping, and Creating a Shadow from an Alpha Channel
This 4-part demo (playlist) will show you how to refine complex edges in masks using CC 2017 tools. This is a daunting task without this method! It follows the lessons in Chapter 6 of the Adobe Photoshop Classroom in a Book 2017 edition.
Masks on a Deeper Level
Learn about masks and channels in-depth in this 6-part video lecture demo. Each video is 5 minutes a piece. While these demos are done in a much older version of Photoshop, the tools and principles are still the same! To truly understand the how masks/channels work, watch these videos. The newer Photoshop book versions don’t really go into this information.
