“Sunny 16” exposure guideline

On a bright sunny day, to get a good, correct exposure shooting at f16 your iso and shutter speed will be the same.

For example at f1:
iso 100 shutter speed will be 1/100
iso 200 shutter speed will be 1/200

so for same shutter and iso on:
slightly over cast use f11  (shadows are soft around the edges)
overcast use f4 (shadows barely visible)
heavy overcast use f4 (no shadows)
