F2, F2.8, F4, F5.6, F8, F11, F16, F22
F2 is suitable if you are taking a photograph of an individual as it has a shallow depth of field, as this means they will be completely in focus, however this F stop isn't suitable for taking a group photograph, this is because some of the people will be blurred, therefore for a group photograph, f stop 16 and 22 are more suitable as this means that everyone will be in focus and it will be a clear photograph. Changing the aperture is important as it is able to show a wide depth of field, which means its able to show the detail in the photograph. For example, a photographer who takes photographs at a wedding will change the aperture and adjust the depth of field depending on the amount of activity and people within the photograph, as well as blurring out anything that is in the background which isn't meant to be there, an example would be someone trying to get in the photograph that isn't meant to be there.
