Which editing approach preserves the original image data while applying edits?

• A. Non-Destructive Editing
• B. Destructive Editing
• C. Pixel Editing
• D. Permanent Changes

Answer: (A)

Non-destructive editing keeps the original image data intact by applying changes through separate, reversible instructions rather than altering the actual pixels on the same layer. In Photoshop, this approach uses tools like adjustment layers to apply color and tonal corrections without changing the underlying pixels, layer masks to reveal or hide edits without erasing pixels, and Smart Objects to preserve original image data when transforming or filtering. Because the original pixels remain untouched, you can tweak, disable, or revert edits at any time without losing the source image. Destructive editing, by contrast, changes pixel values directly—erasing, painting, flattening, or merging layers—so the original data is lost or harder to recover. Pixel editing and permanent changes imply direct modification of data as well, which does not preserve the original image.
