Operating instructions

5.6.1 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.

5.6.2 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.
