How do you adjust the aperture on a Nikon D3200 camera?

To adjust the aperture on a Nikon D3200 camera, you can use the command dial located on the top right of the camera body. Turn the dial to change the aperture setting, which is represented by the f-stop numbers on the camera's display screen. A lower f-stop number means a larger aperture opening, allowing more light to enter the camera. Conversely, a higher f-stop number means a smaller aperture opening, resulting in less light entering the camera.
