I know this is an example of fast shutter speed because in order for someone to have taken a picture of this girl jumping and the powder/ chalk in the air with her they would have needed the camera to have a faster shutter speed to capture it all, they would of also needed the shutter speed to be fast because it is action and just like the action is fast the shutter speed needs to be

as well.

This image is an example of using a slow shutter speed to get that blurry look, because when someone is moving at a fast speed and the shutter is contrasting that by moving at a slow speed you get a blurred look that most photographers use to their advantages.            

This an example of the difference between a wide aperture and a narrow aperture. In the one where the photographer used a more narrow aperture lens which is 1.8, they successfully managed to blur out the background making the female the main focus. In the picture where the photographer decided to use a wider aperture lens they made both the female and the background in focus.

This picture shows us the difference between a shallow and deep depth of field. If you want a deep depth field you would have to use a more narrow aperture, in doing so it blurs the background and gives you a deeper depth of field. If you were to want a more shallow depth of field you would need to use a wider aperture.
