Mastering Non-Destructive Editing

Destructive editing burns your decisions into pixels; non-destructive editing keeps decisions as instructions layered on top of untouched source. The practical difference shows up two weeks later, when the client asks for the original color back and you either click one eye icon or start over.

Three tools cover ninety percent of non-destructive work: adjustment layers for color and tone, masks for visibility, and smart objects for transforms. Learn to reach for these before any direct edit, and your layer stack becomes a readable history of intent.

The habit to build is separation: one layer, one job. The moment a layer both holds content and carries an effect, you've welded two decisions together — and someday you'll need to change exactly one of them.
