Metering Modes
Each time a spot meter reading is taken, the spot meter readings taken so
far are averaged and the result (shutter speed and aperture) is displayed
below the viewfinder. See the figure on the next page for "Multi-Spot
Metering Display." On the exposure compensation scale on the right of
the viewfinder, the exposure level indicator moves around in real-time to
indicate the spot meter reading's current exposure level. Each spot meter
reading is also indicated on the scale with a fixed (non-moving) metering
mark.
