How to use
Background Container
This action creates a Layer group “Background Container”. It is dependent on the PS feature Subject Selection.
This group will have a layer mask applied in the shape of your subject. You may need to refine the mask to get it exactly right, by default only works as good as the Subject Selection feature.
Inside this group by default is a Solid color layer you can use to alter your background color, it’s set to Soft Light to blend with your current background. Play with the color to see the effect.
Anything you add into this folder, will affect just the background. So if you wanted apply more adjustments to the background only, this is useful. Such as overlays, curves adjustments, or even background text and patterns.
