Metering and ExposureTHE F/16 RULE

On a bright sunny day, with your subject front-lit, set the camera’s aperture to f/16. The correct shutter speed is the speed that matches the ISO setting on your camera.

For example: sunny day, front lit subject, camera lens is set on f/16, camera ISO is set at 200… set your shutter speed at 1/200th for the correct exposure.
