How To :: Sunny 16 Rule
So, you’ve got a rocking old camera off of Ebay or a garage sale and oh snap, it’s got no meter. Well meine freunde, it’s about time for you to get acquainted with the Sunny 16 rule.
It states that, on a sunny day, you can set your aperture to f/16 and your shutter speed equal to your film ASA speed. So, if you’re rocking downtown on a bright day and shooting 100ASA Fuji, then set your aperture to f/16 and your shutter to 1/125. This Apogee page has a nice & smooth description of how it all works.
