5.1.8 Automatic TTL fill-in flash mode

For most camera types, automatic TTL
fill-in flash is activated in programmed
auto mode P and variable or subject
programme in daylight conditions (see
camera operating instructions).
With fill-in flash you can remove annoy-
ing shadows, and in back-lit shots a
balanced exposure can be achieved
between subject and background. A
computer-controlled measuring system
on the camera ensures appropriate
combina-tions of shutter speed, wor-
king aperture and flash output.
+
Ensure that the backlight source is not
shining directly into the lens. This will
k
interfere with the camera's TTL mete-
ring.
There is no adjustment or display for
automatic TTL fill-in flash on the flash
unit in this instance.

5.1.9 Manual flash exposure correction
in TTL flash mode
+
This function must be configured on
the camera, see camera operating
instructions.
The automatic flash in most cameras is
set to 25% reflectance
(average reflectance of flash subject).
A dark background which absorbs a lot
of light or a light background which is
heavily reflective (e.g. backlit shots)
can cause the subject to be over or
underexposed.
To compensate for the above effect, the
flash output can be adjusted manually
with the correction value of the shot.
The correction value is based on the
contrast between the subject and the
background.
Hint:
A dark subject in front of a light back-
ground
= positive correction value.
A light subject in front of a dark back-
ground
= negative correction value.
