How to Set Aperture on a Light Meter
The light meter will tell you the best aperture to use on your camera. Remember that the smallest F stop, which is the measurement of an aperture, is the widest aperture. The wider the aperture, the more light the camera will accept. A wider aperture will allow you to use a faster shutter speed. You can follow a few steps to use a light meter to determine the correct aperture.
