On a sunny day the correct exposure is f/16 at 1 over the ASA of the film. So if you are using a film at ASA 32 then set your camera for f/16 at 1/32 (or 1/30 rounded off) for a bright sunny day (Bright or Hazy with distinct shadows). You can extrapolate for weak hazy sun (soft shadows), cloudy bright, open shade or heavy overcast, deeper shade,and sunrise and sunset. You also can adjust for snow.
