M range, shutter 100+, aperture F8, focusing on the subject's face. The larger the aperture value, the clearer the background, but the larger the aperture value, the worse the image quality, depending on your choice, usually F8. If the shooting environment is dark, improving ISO can improve brightness and shutter speed, but the noise is greater.
