After making a selection, you can enhance it by adjusting its softness, roundness, or size using the Refine Selection tool. And using Smart Refine, you can enhance a selection automatically.
Do one of the following:
Note: While the Refine Selection tool is active, your selection outline is replaced by a yellow overlay. Any selected areas are see-through, while any unselected areas are yellow.
Note: For even finer selections, press down the key on your keyboard to turn on the refinement brush mode.
Smart Refine uses an edge-detection algorithm to detect object edges in your image and automatically refines the selection outline for you, snapping it to the nearest edge.
Do one of the following:
Note: While the Refine Selection tool is active, your selection outline is replaced by a yellow overlay. Any selected areas are see-through, while any unselected areas are yellow.
Adjust the options in the Tool Options pane:
Note: As long as Smart Refine is turned on, edge-detection is always active, even when you move the sliders in the Tool Options. So when you change the size, softness, or roundness of your selection, it will carry on snapping to the object’s edges.
Click Apply at the bottom of the Tool Options pane to apply your refinements to the selection.
While the Refine Selection tool is active, paint over areas in your image to quickly edit your selection.
If the Add selection mode is active, any areas you paint over will be added to your selection (and lose the yellow overlay).
If you choose the Subtract selection mode, the areas you paint over will be removed from your selection (and will be covered by the yellow overlay).
Note: For even finer selections, press down the key on your keyboard to temporarily switch to the refinement brush mode.
