Which term describes the range of distances in an image where objects appear acceptably sharp?

• A. Focus
• B. HD Resolution
• C. Depth of field
• D. Sensor

Answer: (C)

Depth of field describes the range of distances in a scene that appear acceptably sharp in the image. It’s not just the exact plane you focus on—the area in front of and behind that plane still looks reasonably sharp, within the limits set by the camera settings. The extent of this range changes with aperture, focal length, and how far you are from the subject. A smaller aperture (higher f-number) increases depth of field, a shorter focal length (wide-angle) lens also broadens it, and moving farther from the subject generally increases it. Focus itself is the single distance where the image is sharpest; depth of field is the surrounding zone that remains acceptably sharp. HD resolution and sensor are about image quality and hardware, not the range of distances that stay sharp.
