Large lens openings give you _____ depth of field.

Explanation:
A wide aperture makes the depth of field shallower—that is, only a small slice of the scene is in sharp focus while everything in front of and behind that plane becomes blurry. When you open the lens wide (low f-number), more light enters, and the focus plane narrows, so background and foreground blur increases. This is why portraits often use a large opening to isolate the subject from a soft background. If you want more of the scene in focus, you stop down to a smaller aperture, which broadens the depth of field. Therefore, large lens openings give you less depth of field.
