What are the recommended camera settings for achieving a shallow depth of field with an aperture of f 4 5.6?

To achieve a shallow depth of field with an aperture of f/4-5.6, you should set your camera to a lower f-stop number (such as f/4) and use a longer focal length. This will help create a blurred background while keeping your subject in focus. Additionally, you can adjust your ISO and shutter speed to ensure proper exposure.
