Automatic Ttl Fill-In Flash In Daylight; Canon E-Ttl Flash Mode - Metz MECABLITZ 36 AF-3 C Mode D'emploi

5.7.1 Automatic TTL fill-in flash in daylight

Most camera models automatically activate the fill-in flash
mode when in Full Auto Mode, Program P, and the
Programmed Image Control Modes in daylight (see the
camera's operating instructions).
Fill-in flash overcomes troublesome dense shadows and
produces a more balanced exposure between subject and
background with contre-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 meca-
blitz for automatic TTL fill-in flash.

5.7.2 Canon E-TTL flash mode

With mecablitz 34 AF-4 C only
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). The measuring
preflash does not contribute to the exposure.
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.
