Final answer:
The position at which the aperture is set is represented by the f-stop. Aperture is the size of the opening in a camera lens that controls the amount of light reaching the camera's sensor. It is measured in f-stops.
Step-by-step explanation:
The position at which the aperture is set is represented by the f-stop.
Aperture is the opening in a camera lens that can be made bigger or smaller to let more or less light through the lens. It is measured in f-stops. A smaller f-stop number means a larger aperture, allowing more light to enter the camera, while a larger f-stop number means a smaller aperture, allowing less light to enter.
