What is a clipping mask, and how would you apply it in Photoshop or Illustrator?

• A. A clipping mask hides content outside a shape and crops the image permanently.
• B. A clipping mask is the same as a layer mask.
• C. A clipping mask can only be used with text layers.
• D. A clipping mask reveals content within the bounds of a mask shape; apply by placing the mask shape above the content and choosing Clipping Mask.

Answer: (D)

A clipping mask creates a visible window for artwork using a shape. The mask shape defines exactly which parts of the content beneath stay visible; everything outside that shape is hidden, but the underlying content remains intact.

To apply it, place the shape above the content you want to reveal, then create the clipping mask.

• In Photoshop: select the shape layer and the layers to clip, then Layer > Create Clipping Mask (or right-click > Create Clipping Mask). The lower content is shown only where the shape overlaps.

• In Illustrator: select the mask shape and the artwork beneath, then Object > Clipping Mask > Make. The artwork is clipped to the mask’s outline.

This is non-destructive and can be released later to edit either the mask or the content.
