Sean Duggan explains some key concepts that govern how layer blend modes work, including why they are grouped in specific arrangements, and how different groups of blend modes will have similar effects on underlying layers. He shows how the colors of black, white, and 50% gray function as neutral colors for different blending modes, rendering them invisible when the correct blend mode is used. He shows how to take advantage of blend mode neutral colors to create interesting collage and compositing possibilities.
- [Voiceover] In this chapter, we're going to…explore some of the possibilities that…layer blending modes can provide…for creating composite images.…We'll start with a quick review…on a few important concepts that are key…to understanding how to take advantage…of the compositing power that blend modes have to offer.…In this file, I have a background image,…and on top of that I have a layer…that has three shapes, and those shapes…are filled with black, middle gray, or 50% gray…to be precise, and white.…
The reason I have these shapes here…is because those three colors serve as…neutral colors for certain blending modes,…and a neutral color means that…the blend mode doesn't see it.…It acts as if that color isn't there at all,…and it will totally disappear when you use…a certain blend mode.…Let's open up the blending mode menu…at the top of the layers panel,…and the first thing to notice is that…the blending modes are separated into distinct groupings,…based on the type of effect that they have on the image.…
For our explorations here in using blending modes…
