Automatic Ttl Fill-In Flash In Daylight; Canon E-Ttl Flash Mode - Metz MECABLITZ 36 AF-5 C Mode D'emploi

If flash exposure was correct, the "o.k." exposure confirma-
tion lights up.
The TTL flash mode is supported by all camera modes (e.g.
Full Auto Mode, Program P, Aperture Priority Mode "Av" or
"A", Shutter Priority Mode "Tv" or "S", Programmed Image
Control Modes, Manual Mode "M", etc.).
To test the TTL function a film must be loaded in the
camera. When selecting the film please check whether
limits regarding maximum film speed are applicable
to the given camera when in TTL mode (refer to the
camera's operating instructions). The mecablitz sup-
ports the TTL flash mode for film speeds from
ISO 25 to ISO 800.

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 pro-
duces a more balanced exposure between subject and back-
ground with contre-jour shots. The camera's computer-con-
trolled metering system sets the most suitable combination 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.

5.7.2 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). The measuring preflash
does not contribute to the exposure.
