The F16 rule is ASA speed equal shutter speed @ F16 in bright daylight.
Experience dictates variables from that point. Cloud cuts off the sun,
drop to F8 etc.

Is the other part of that rule of thumb that you set the exposure time
for 1/the lens length? I.e., if you're using a 75mm lens, set the
exposure time 1/75 (or as close as you can get).
