Aperture is measured in f-stops, with lower f-stop numbers indicating a larger aperture opening and higher f-stop numbers indicating a smaller aperture opening. A larger aperture (lower f-stop) results in a shallow depth of field, while a smaller aperture (higher f-stop) increases the depth of field.

Using Aperture Creatively

By adjusting the aperture settings, photographers can create different effects in their photos. A wide aperture can be used to isolate a subject from the background, while a narrow aperture can be used to capture sharp details throughout the image.
