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 information 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 metering is selected). Tip 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. Camera Settings: Metering 41

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.
