Combine, refine and copy masks

Film recorded with an earlier version; the written reference is current.

0:03 Start with a broad radial selection
Several shapes can share one local correction.

0:09 Show coverage before combining
You need to see the selection, not just the outlines.

0:16 Open Shapes & overlay
The shape icons here add to the active local.

0:23 Add a second radial
Add includes areas covered by either shape.

0:30 Place the second shape
Here the two ellipses overlap.

0:36 Intersect keeps only the overlap
Shape order matters when you build a selection.

0:42 Subtract protects the second shape
It removes that shape from the earlier coverage.

0:48 Exclude removes the shared area
Only the non-overlapping parts remain selected.

0:54 Return to Add
Choose the operator that matches the correction you need.

1:00 Ranges can narrow this geometry
A range tests pixel values inside the shapes.

1:07 Reveal the individual bands
Luminance, Hue and Colour each have limits and falloff.

1:13 Restrict the mask to brighter pixels
Soft falloff avoids a hard tonal cut-off.

1:19 Inspect the finished edge controls
Blur softens; Refine edge follows nearby image detail.

1:26 A small blur softens the finished mask
Mask contrast and brightness change coverage, not image tone.

1:32 Apply a restrained correction
Check coverage, then judge the photograph.

1:38 Copy the complete local
Copy includes shapes, ranges and correction values.

1:45 Use the mask copy button
Paste on another photo with Ctrl+Shift+V; check its placement.

1:52 Hide the mask display
The correction stays active while you review it.
