What are examples of non-destructive editing?

• A. Flattening the image
• B. Using Adjustments layers, Transforming Smart Objects, and Masking
• C. Using the Clone Stamp and Eraser
• D. Destructive edits via Image > Adjustments

Answer: (B)

Non-destructive editing keeps the original image data intact so you can tweak or revert edits later. The best examples are using adjustment layers, transforming Smart Objects, and masking. Adjustment layers apply color and tonal changes on separate layers you can edit, hide, or remove without changing the pixels themselves. Smart Objects preserve the original content, so when you scale, transform, or edit them, you’re not permanently altering the source data—you can go back and edit the object later. Masking hides or reveals parts of a layer without erasing pixels, and masks can be adjusted or disabled at any time, preserving detail.

In contrast, flattening the image merges all layers into one, destroying the layer structure. The Clone Stamp and Eraser paint directly on pixels, altering them permanently. Edits made via Image > Adjustments also affect pixels on the layer itself, which is destructive. So the combination of adjustment layers, Smart Objects, and masking represents non-destructive editing.
