What does the term 'non-destructive editing' mean in Photoshop?

Non-destructive editing in Photoshop refers to the process of making adjustments or edits to an image without permanently altering the original pixel data. This approach allows for flexibility and creativity, as edits can be modified or removed at any point in the workflow.

When using non-destructive techniques, such as adjustment layers, masks, or smart objects, you maintain the integrity of the original image. This means that you can always revert to the unedited version of the image if needed, making it a crucial practice for photographers and designers who might want to make additional changes later.

The other choices suggest methods that involve direct changes to the original image data, which can limit further editing and could potentially lead to loss of quality or detail. Non-destructive editing empowers users to experiment and refine their work with ease and confidence.
