There are three exposure metering modes: In the “A” mode the average brightness in the en- tire frame is measured with emphasis on the center of the frame. The brightness at a specific spot in the center of the frame is metered in the “S” mode. The “A-S” mode automatically switches between these two modes depending on the contrasts in the picture.
