Exposure

Metering

Metering determines how the camera sets exposure. The
following options are available:
Option
Matrix: Produces natural results in most situations. Camera
meters a wide area of the frame and set exposure according to
tone distribution, color, composition, and, with type G, E, or D
L
lenses (0 422), distance information (3D color matrix metering
III; with other CPU lenses, camera uses color matrix metering III,
which does not include 3D distance information).
Center-weighted: Camera meters entire frame but assigns greatest
weight to center area (if CPU lens is attached, size of area can be
selected using Custom Setting b6, Center-weighted area,
M
0 317; if non-CPU lens is attached, area is equivalent to circle
12 mm in diameter). Classic meter for portraits; recommended
when using filters with an exposure factor (filter factor) over 1×.
Spot: Camera meters circle 4 mm (0.16 in.) in diameter
(approximately 1.5% of frame). Circle is centered on current
focus point, making it possible to meter off-center subjects (if
N
non-CPU lens is used or if auto-area AF is in effect, camera will
meter center focus point). Ensures that subject will be correctly
exposed, even when background is much brighter or darker.
Highlight-weighted: Camera assigns greatest weight to highlights.

Use to reduce loss of detail in highlights, for example when
photographing spotlit performers on a stage.
