SPOT
This metering method is concentrated exclusively on a small area
in the center of the image. The metering fields are joined together
when the exposure metering method

at the point specified by the AF metering field, even if it is moved.
CENTER-WEIGHTED
This method considers the entire image field. The subject elements
captured in the center will, however, impact on the calculation of the
exposure value more so than areas around the edges.
MULTI-FIELD
This metering method is based on the detection of multiple values.
These values are used in an algorithm to calculate an exposure value
appropriate for a good rendering of the assumed main subject.

HIGHLIGHT-WEIGHTED
This method considers the entire image field. The exposure value
will, however, be adjusted to very bright subject elements. That
prevents the overexposure of bright subject elements without having
to measure them individually. This metering method is particularly
useful for objects that are significantly more brightly lit than the rest
of the frame (e.g. people in a spotlight), or that reflect the light sig-
nificantly (e.g. white clothing).
