Manual Flash Exposure Correction - Metz Mecablitz 64 AF-1 digital -Olympus-Panasonic-Leica Bedienungsanleitung

8 Manual flash exposure
The auto flash exposure mode of most came-
ras is adjusted to a reflection factor of 25%
(the average reflection factor of flash sub-
jects).
A dark background that absorbs much of the
light or a highly reflective bright background
(backlit shots, for example) may result in,
respectively, underexposure or overexposure
of the subject.
To offset these effects, the flash exposure
can be adjusted manually for the shot with a
correction value. The extent of the correction
depends on the contrast between the subject
and background!
In A/TTL flash modes, manual flash exposure
correction factors of from -3 EV (f-stops) to +3
EV (f-stops) can be adjusted on the flash unit
k
in one-third increments.
Tip:
Dark subject against light background: posi-
tive correction factor.
Light subject against dark background:
negative correction factor.
Exposure correction by means of alteration of
the lens aperture setting is impossible, since
the camera's automatic exposure program
regards the altered aperture setting as the
normal working aperture setting.

For some camera models, the manual flash
