giving special weighting to a particular area. Use this setting in scenarios with
even lighting conditions.

camera will use the light information coming from the horizon to determine its

coming from directly above (e.g. indoors with bright ceiling lighting or outdoors
with bright sunlight coming from directly above) and if you want to achieve the
most correct balance of light and exposure for objects at the horizon. This mode
is the default setting. Compared to even weighted metering, this mode will
increase scan duration by approximately 14 seconds.
If the vertical scan area is limited, then the area used to determine the exposure
(exposure metering area) might move away from the horizon. This is the case if
the vertical start angle is set to a value > -30° or if the vertical end angle is set to
