Which term denotes the numeric value that represents the camera's aperture?

• A. Aperture Size
• B. Aperture Value
• C. F-Stop
• D. Shutter Speed

Answer: (C)

The numeric value that represents how big the lens opening is called the f-stop (also known as the f-number). It’s a ratio that compares the focal length to the diameter of the aperture, so smaller numbers like f/2.8 mean a larger opening and more light, while larger numbers like f/16 mean a smaller opening and less light with greater depth of field. This labeling is the standard way photographers communicate aperture settings. Terms like “Aperture Size” describe the physical opening but aren’t the conventional numeric label, while “Aperture Value” isn’t the common term used in practice. Shutter speed, on the other hand, controls how long the sensor is exposed to light, not how big the opening is.
