Adjusting the aperture
If the difference between the brightness of the subject and the background is too great, adjust the aperture manually.
When the aperture opens (lowering the F value), focal point becomes smaller (reducing depth of field) so that the background will blur and the subject will be in focus [a]. When the aperture closes (raising the F value), focal point becomes greater (increasing depth of field) so that both background and subject will focus clearly [b].
