Large lens openings produce which depth of field?

Explanation:
Opening the aperture wide reduces depth of field. Depth of field is the range of distances that appear acceptably sharp in an image. A large aperture lets in more light but narrows the focus plane because the circle of confusion for points away from the focus grows larger. In practical terms, you get a sharp subject with a noticeably blurred background or foreground—great for portraits. If you want more of the scene in focus, you stop down to a smaller aperture, which increases depth of field. So, large lens openings produce less depth of field.
