Which term describes the parameter that quantifies how large the opening of the lens is?

• A. Aperture
• B. HD Resolution
• C. F-Stop
• D. Exposure

Answer: (C)

The size of the lens opening is quantified by the f-stop. The f-stop, or f-number, is the numerical value that expresses how wide the aperture is. A smaller f-number means a larger opening and more light entering the camera; a larger f-number means a smaller opening and less light. This single parameter directly controls exposure and depth of field because it determines how much light passes through the lens. The aperture is the actual opening, but the f-stop is the measurement that quantifies its size. HD resolution and exposure describe other aspects—resolution is image detail, and exposure is the overall light reaching the sensor influenced by aperture, shutter speed, and ISO.
