Nikon D1 User Manual

Spot metering: The camera measures light only in a circle 4mm
(0.15˝) in diameter and centered on the current focus area. The area
metered occupies approximately two percent of the entire frame.
This method can be used with back-lit subjects or on other occasions
when the background is much darker or much brighter than your
subject.
As a rule, spot metering measures light in the current focus area,
ensuring that your subject is properly exposed. When closest-
subject priority is used with dynamic AF area selection, or when a
non-CPU lens is attached, light will be measured in the center focus
area only.
To choose a metering method, hold the metering
selector lock release down and rotate the metering
selector to the desired setting.
Tip
Camera Settings: Metering
Some lenses do not support one or more of the above metering systems. See
“Technical Notes: Compatible Lenses” for more information.
