Exposure
Metering determines how the camera sets exposure. The
following options are available:
Metering
Option Description
L
Matrix : Produces natural results in most situations. Camera meters
wide area of the frame and sets exposure according to tone
distribution, color, composition, and, with type G, E, or D lenses
(
0 323), distance information (3D color matrix metering III; with
other CPU lenses, camera uses color matrix metering III, which
does not include 3D distance information).
M
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,
0 302;
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×.
N
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 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.
t
Highlight-weighted : Camera assigns greatest weight to highlights.
Use to reduce loss of detail in highlights, for example when
photographing spotlit performers on-stage.
