Nikon D70 Mode D'Emploi

In P, S, A, and M modes, the metering mode determines how the camera sets 
exposure.  The following options are available when a CPU lens is attached 
(metering is not performed when a non-CPU lens is used).

Camera meters circle 2.3 mm (0.09˝) in diameter (approximately 1% of 
frame).  Circle is centered on current focus area, making it possible to 
meter off-center subjects (if Closest subjct is selected for AF-area mode, 
camera will meter center focus area).  En sures that sub ject will be cor-
rectly ex posed, even when back ground is much brighter or darker.

Spot

Camera meters entire frame but assigns greatest weight to area in center 
of frame 8 mm (0.31˝) in diameter, shown by corresponding 8-mm refer-
ence circle in viewfi nder.  Classic meter for portraits; recommended when 
using fi lters with exposure factor (fi lter factor) over 1 × (

 191).

Center-

weighted

Metering is performed by 1,005-pixel RGB sensor, which sets exposure 
based on variety of information from all areas of frame.  This method is 
particularly effective where frame is dominated by bright (white or yel-
low) or dark (black or dark green) colors, when its results approach what 
is seen by human eyes.  3D color matrix metering, which uses range infor-
mation from lens in adjusting exposure, is available only with type G or D 
lenses.  Color matrix metering, which does not include range information, 
is available with other CPU lenses.  Matrix metering will not produce 
desired results with autoexposure lock (

 84) or exposure compensation 

(

 86), but is recommended in most other cases.
