Canon E-Ttl Flash Mode - Metz MECABLITZ 24 AF-1 C digital Bedienungsanleitung

5.6.2 Canon E-TTL flash mode

The E-TTL flash mode is an advanced variant of the "normal"
TTL flash mode. Prior to shooting, the reflection of the subject is
measured by way of a preflash. The camera evaluates the
reflected preflash light so that the subsequent flash exposure is
optimally adapted to the prevailing photographic situation (see
operating instructions of your camera).
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 expo-
sure 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
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
