4.8 TTL flash exposure correction (manual
TTL flash exposure correction)
There are certain photographic situations where
the camera’s internal sensor can be deceived. This
is particularly the case with a dark subject in front
of a bright background (the subject will be under-
exposed) or a bright subject in front of a dark back-
ground (the subject will be overexposed). To over-
come this problem in such a photographic situation
and still achieve a correct exposure in the TTL flash
mode, some cameras permit the flash intensity to
be influenced in the TTL and TTL fill-in flash modes
(also see operating instructions for the given
camera). On flash units with an LC display
(40 MZ-..., 44 MZ-2, 50 MZ-..., 54 MZ-...,
70 MZ-.... and 76 MZ-5 digi) the indicated maxi-
mum flash range is adapted to the selected flash
exposure correction in the TTL and A modes.
Manual TTL flash exposure correction is possible
with the following cameras: Dynax 9, 7, 800si,
700si, 600si and is set on the camera. The setting
procedure for a manual TTL flash exposure correc-
tion is described in the user’s manual of the given
camera.
With the digital cameras Dimage 5, 7, 7i, 7Hi, flash
exposure correction is set on the camera (see
user’s manual).
