Retouch Backgrounds and Objects
By the end you can plan a retouch on paper before the software opens; run an AI background extraction as a directed first pass, bring it into GIMP as a layer mask over the original, and name at full zoom where it failed; clean a difficult edge by hand on the mask so the original pixels survive; vanish an object with clone and heal on its own repair layer so a person who knows the photo cannot find it; export each product with transparency and on white, paired with its original under one stem; and keep the receipts and the label on every piece.
