Which technique lets you modify an image without overwriting the original image data?

• A. Destructive editing
• B. Rasterization
• C. Flattening
• D. Nondestructive editing

Answer: (D)

The main idea is to edit in a way that keeps the original pixels intact. Nondestructive editing achieves this by applying changes on separate layers, masks, or smart objects instead of directly altering the original image data. For example, you can use an adjustment layer to change brightness or color without changing the underlying pixels, and you can tweak or remove that adjustment later. Layer masks let you hide or reveal parts of a layer without erasing, and smart objects let you transform or filter a layer while preserving the original image inside the object. This approach gives you the freedom to revise or revert edits at any time because nothing is permanently baked into the original image. Destructive approaches, by contrast, modify the actual pixel data, making it harder to reverse. Techniques like painting directly on the image, erasing, or flattening layers permanently change the original content. Rasterizing converts vector data to pixels, which can limit future edits. The reason nondestructive editing is the best fit here is that it keeps the original image safe while you experiment and refine.
