Metz MECABLITZ 36 AF-5 C Mode D'emploi page 88

Settings and displays
• Switch on the flash unit and the camera.
• Lightly touch the camera's shutter release for data exchan-
ge between flash unit and camera.
• The E-TTL flash mode is automatically activated when the
camera supports this mode. E-TTL then lights up on the
flash unit.
FE flash exposure storage
Some Canon cameras offer the possibility of FE flash exposu-
re storage. This is supported by the flash unit in the E-TTL
flash mode.
FE flash exposure storage in E-TTL mode permits the amount
of light required for the subsequent shot to be determined
and stored prior to exposure. This can be expedient when
flash exposure has to be adapted to specific details that may
not necessarily be identical with the main subject.
Focus the camera's AF sensor metering area on the zone
whose flash exposure is to be predetermined. When the FE
88
button on the camera is actuated (the designation may vary
with individual camera models - see camera's operating
instructions) the flash unit will fire an FE test flash. The electro-
nic measuring circuit inside the camera assesses the reflected
light of the FE test flash to determine the light output required
for the subsequent exposure. The main subject can thereafter
be focused with the AF sensor metering area of the camera.
When the shutter release is pressed the picture will be expo-
sed with the previously determined light output.
Due to system-inherent reasons any changes in the light situ-
ation after the FE test flash has been fired will not be taken
into account when the picture is shot.
Some cameras do not support FE flash exposure storage in
the "green" full auto mode or programmed image control
modes (see camera's operating instructions).
