Pixelmator Pro tutorial: refine AI background removal

This beginner tutorial explains how to remove a photo background in Pixelmator Pro and repair areas that the automatic selection misses. The speaker starts with Edit > Remove Background, also available through Shift Delete or a toolbar icon. In the example, the result has rough edges around fine details and loses part of the subject's shorts.

For more control, the speaker undoes the removal, duplicates the image layer with Command J, and uses Select Subject. They explain that it produces the same initial outline while keeping the selection visible for editing. The tutorial also shows how to add Select Subject through Customize Toolbar.

Quick Selection, accessed with Q, restores larger missing areas. Holding Option while brushing subtracts unwanted areas. The speaker then opens Select and Mask and uses the edge refinement brush around hair and boundaries that blend into the background. Brush size can be adjusted with the control or bracket keys; the speaker leaves softness at its existing setting.

After applying the refinement, the speaker uses Command J to copy the selected subject to a layer and Command D to dismiss the selection outline. A replacement background goes beneath the cutout. The closing advice is to adjust lighting or colors to match, though the tutorial does not demonstrate those adjustments in detail.
