What is Mask Edge and how do you feather the edges of a mask?

• A. Mask Edge is a color adjustment for masks
• B. Mask Edge controls opacity of a mask
• C. Mask Edge is the keyboard shortcut for refine edge
• D. Mask Edge refers to the boundary of a layer mask; feather the edges by selecting the mask and applying Feather

Answer: (D)

Mask Edge refers to the boundary of a layer mask—the line where the mask’s effect transitions from fully visible to fully hidden. Feathering that boundary softens the edge so the transition looks natural rather than a hard cut. To feather, select the mask thumbnail in the Layers panel to activate the mask, then apply Feather. You can adjust this in the Properties panel by moving the Feather slider, or use the Select and Mask/Mask Edge workspace to blur the edge. This creates a gradual transition that helps blend the masked element with its surroundings.
