Metering
The D1 offers a choice of three metering methods, which can be chosen
according to how your subject is lit:
Color matrix metering/3D color matrix metering: The D1 uses a
3D color matrix metering system. In this system, metering is
performed by a CCD sensor with 1,005 (67 vertical × 15 horizontal)
metering pixels, which sets exposure using a selection of data from
all areas of the frame. This system is particularly effective with
brightly-colored (white or yellow) or dark-colored (black or dark
green) subjects that occupy a substantial portion of the frame,
producing photographs closer to what is seen by the naked eye. 3D
color metering can however only be used with D-type lenses. When
another type of lens is in place, color matrix metering is used. Unlike
3D matrix metering, this system does not make use of range informa-
tion from the lens.
Spot or center-weighted metering is recommended when you use
AE-lock (see “AE Lock”) or exposure compensation (see “Exposure
Compensation”).
Center-weighted metering:
The camera measures
light in the entire frame, but assigns the greatest
weight to a circular area in the center of the viewfinder
8mm (0.31
˝) in diameter (the 12mm/0.47˝ circle in
the center of the viewfinder, shown at right, can be
used as a reference when center-weighted meter-
ing is selected).
Tip
Camera Settings: Metering
The size of the area given the greatest weight in center-weighted metering can be
set to 6mm
(0.24
˝), 10mm
(0.39
˝), or 13mm
(0.51
˝) (see “Custom Settings,” item
14). Alternatively, you can set center-weighted metering to use the average of the
entire frame. The default setting is 8mm.
