Answer and explanation

Correct answer: D. The distance between the nearest and farthest objects in a scene that appear acceptably sharp in focus

  1. Step 1: Depth of field is the optical zone of acceptable sharpness in front of and behind the focal plane. Step 2. Shallow depth of field isolates a sharp subject against a blurred bokeh background; deep focus keeps foreground and background sharp. Answer: The distance between the nearest and farthest objects in a scene that appear acceptably sharp in focus. Why not the others: It is an optical property of lenses and apertures, not narrative psychology.
