A simple way to make detailed layer masks is with Exposure’s 3d color constraints. Layer masks expand your control over applying edits. They enable you to quickly place edits on the foreground, the background, or whichever area you choose.
Check out this video for a demonstration in making layer masks with color constraints. We’ll show you the essentials for targeting color regions in the image using three separate dimensions. In addition, we share a few important keyboard shortcuts that help you dial-in adjustments made to the mask with greater accuracy.
