The low f-stop value like this will isolate the foreground subject from the background. This means it has a wider aperture and a smaller depth of field. The shutter speed is so fast that the motion in the shot looks like it’s frozen in time.

Shutter speed: 1/4000

Aperture: 2.8

ISO setting: 6400

Because of the slow shutter speed in this image, it not only makes moving things seems more blurry but also makes the image brighter. In this case the image in not brighter as the ISO setting is quite low, this makes the image seem more clearer and is darker.

Shutter speed: 1/3

Aperture: 22

ISO setting: 400

Depth of field determines which parts of your photo are in focus and aperture lets you control that depth of field. Adjusting the focus can lead to sharper images, or, if handled in a specific way, create depth of field and emphasize just one part of an image while blurring everything behind it. to do this is by usually turning a focus ring on the lens. Adjusting the focus yourself is called manual focus. It can be advantageous to use it in a few different situations. But in most situations autofocus is incredibly convenient as well, it does have its downsides though. the control of aperture itself can be adjusted to let in more or less light. A small aperture lets in less light and leads to a darker image, while a larger one can flood the sensors with light.
