What is the difference between an f-4 and an f-16 setting in a camera?

Answer 1

The f-stop (aperture) setting of a camera, such as f/4 and f/16, controls the size of the lens opening and affects exposure and depth of field. An f/4 setting allows more light to enter the camera, resulting in a brighter image and a shallower depth of field, which can create a blurred background. In contrast, an f/16 setting lets in less light, produces a darker image, and increases the depth of field, keeping more of the scene in focus. This choice impacts the overall look and mood of the photograph.
