Which term describes the clarity of the subject in the image?

• A. Focus
• B. Depth of field
• C. Exposure
• D. Resolution

Answer: (A)

Clarity of the subject in a photo is determined by focus. When the lens is correctly focused on the subject, its edges and details render crisply, making the subject appear sharp. Depth of field describes how much of the scene around the subject is in acceptable sharpness—how many things in front of and behind the subject stay reasonably clear—not whether the subject itself is sharp. Exposure affects how bright or dark the image is and can influence perceived detail, but it doesn’t control sharpness. Resolution refers to how much detail the sensor and image contain; a higher resolution can show more detail, but a misfocused shot will still look blurred even at high resolution. So, focus is the term that best describes the subject’s clarity.
