Exposure
Metering
Metering determines how the camera sets exposure. The following options are available:
Matrix: Produces natural results in most situations. Camera meters a wide area of the frame and set exposure according to
Ltone distribution, color, composition, and, with type G, E, or D 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
Mselected using Custom Setting b6, Center-weighted area,
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
Nfocus 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.
Highlight-weighted: Camera assigns greatest weight to highlights.
