average e ttl flash metering

Average metering takes all of the light values for a given scene—highlights, shadows, and mid-tones—and averages them together to establish an overall exposure. Average metering is best used for front-lit subjects under average lighting conditions. Backlit subjects tend to be silhouetted when metered in average mode.
