What's the sunny f16 rule?

The sunny 16 rule is a way of guessing exposure if a meter is not avaiable. The rule states: To find the correct exposure for a bright sunny day (no clouds) you set your f-stop to F-16 and the shutter speed cloest to the inverse of the film speed. Example: 100ISO film the correct exposure would be F-16 @ 1/100 or 1/125. If there are some clouds you would adjust one stop. Overcast day adjust 2or 3 stops, so on and so on. For a sunny day at the beach or snow, you would use F-22. If you look inside a box of film they give you examples of the sunny 16 rule in pictures. I would use it to help you determine if your meter is working correctly. If you start getting weard exposures you may use the sunny 16 rule to figgure if it is close or not.I hope that this helps?
