Pronounced differences in contrast, e.g. a dark
subject in snow, may make it necessary to correct
the exposure settings (see 4.3).
4.1.1 Automatic TTL fill-in flash in daylight
Most camera models automatically activate the
fill-in flash mode when in auto program mode
“P”, Vari or a Scene mode in daylight (see the
camera’s operating instructions).
Fill-in flash overcomes troublesome dense
shadows and produces a more balanced expo-
sure between subject and background with con-
tre-jour shots. The camera’s computer-controlled
metering system sets the most suitable combina-
tion of shutter speed, working aperture and flash
output.
Ensure that the contre-jour light source does
not shine directly into the lens as this will
mislead the camera’s TTL metering system!
In this instance there is no setting or display on
the mecablitz for automatic TTL fill-in flash.
4.1.2 Matrix-controlled TTL fill-in flash
In this flash mode the subject and the background
lighting are automatically balanced without over-
exposing the subject. The camera establishes the
exposure setting for the ambient light by matrix
metering.
Various Nikon cameras support the matrix-con-
trolled fill-in flash mode (see operating instructions
of the camera and Table 1).
Some cameras (F4 or F4s for example) do
not support the matrix-controlled TTL fill-in
flash mode for SPOT exposure metering.
This flash mode will then either be automa-
tically cancelled or cannot be activated, so
that the normal TTL flash mode will be per-
formed.
When using cameras of Group A (see Table 1),
this fill-in flash mode is set and displayed on the
mecablitz.
With cameras of Group B (see Table 1) the setting
is made on the camera, or this flash mode is auto-
matically activated by the camera (see operating
instructions of the camera). There is no such set-
ting made or indication given on the mecablitz.
