For example if you want a 1:1 ratio, choose a fstop/shutter speed for ambient light and then adjust flash power manually until it gives correct exposure with the fstop already in use.
also allows extreme closeup work while keeping the f-stop managable with fast film. third less used feature is the very low power setting allows shortest possible flash duration which is desireable if your trying to freeze extremely fast action of some sort.
