What is the difference between clipping masks and layer masks, and when would you use each?

• A. Clipping mask uses a grayscale to reveal content, while layer mask uses a shape to reveal content.
• B. Clipping mask uses a shape to reveal underlying content; layer mask uses grayscale to hide/show parts non-destructively.
• C. Layer masks crop content permanently; clipping masks adjust color.
• D. Clipping masks are destructive; layer masks are non-destructive.

Answer: (B)

The main idea is how you control what parts of a layer you actually see without changing the pixels. A clipping mask uses the shape of a base layer to reveal the layer above. It creates visibility only where the bottom layer is opaque, so the top content is shown inside that silhouette and hidden outside it. This is ideal when you want, for example, a photo or texture to fill a specific contour or shape defined by another layer. A layer mask, on the other hand, uses grayscale directly on the same layer to control transparency. White areas are fully visible, black areas are fully hidden, and gray areas are partially transparent. This lets you gradually reveal or hide parts of the layer with soft edges or smooth transitions, and you can paint, erase, or apply gradients to refine the mask. It’s a flexible, non-destructive way to sculpt visibility within a single layer. Use a clipping mask when you want the contents of one layer to be restricted to the shape defined by another layer. Use a layer mask when you want precise, adjustable control over the transparency of a layer itself, including soft fades and complex edge treatment. Both methods preserve the original pixels; masks simply control visibility rather than permanently altering the image.
