note:
An exposure compensation set on the camera only
influences the measurement of available light. If you
want to simultaneously use compensation of the
TTL flash exposure measurement in flash mode – in
parallel or in the opposite direction, you must make this
additional setting on the flash unit. See the sections on
flash mode starting on p. 130 for details.

ExAMpLE oF A posITIvE CoMpEnsATIon
With very bright subjects, such as snow or a beach,
the exposure meter selects a relatively short exposure
time due to the extreme brightness. As a result, the
snow shows up in an average gray and any people in
the photograph are too dark: this is under exposure.
To remedy this problem, the exposure time needs to
be extended or the aperture increased, i.e. a setting of
perhaps +1 1 / EV needs to be made.

ExAMpLE oF A nEgATIvE CoMpEnsATIon
For very dark subjects that reflect very little light, the
exposure meter selects an exposure time that is far too
long. A black car will appear gray: this is over exposure.
The exposure time needs to be shortened, i.e. a setting
such as –1EV is required.
