Slave mode with Preflash suppression SL | Metz 28 CS-2 instruction

6.2Slave mode with

preflash suppression SL

This slave mode is specifically intended for digital cameras working with preflash technology. In this mode, the slave flash unit is not triggered by the measuring preflash but only by the main flash from the camera’s internal flash unit at the moment of exposure. The light output of the slave is con- trolled by way of the set flash mode (EASY, auto- matic A or manual M mode).

☞The red-eye reducing preflash function must not be activated on the camera! The slave flash unit will only react to light pulses from the controller within a specific time (fractions of a second) , thus making it almost insensitive to the flash light of other photographers that are not working with preflash technology.

Settings on the slave flash unit

Repeatedly depress the pre-select and “MODE” keys simultaneously until the symbol

SL flashes on the LC display. The setting instantly becomes effective and is automatically stored after 5 s.

☞If necessary, you can modify the suppression of the preflash and reset the time between preflash and main flash for manual adapta- tion to your camera; see also Chapter 11.3.

6.3 Adapted slave mode SL

This slave mode permits individual adaptation of the slave to the technology of the camera’s internal flash unit. It permits one or more red-eye reducing preflashes and one or more measuring preflashes of the integrated flash unit to be taken into ac- count. The slave is triggered at the same time as the camera-internal flash unit firing the main flash for exposure. The light output of the slave unit is controlled by the selected flash mode (EASY, auto- matic A or manual M mode).

Adapting the flash unit

•Activate the integrated flash unit. If necessary, switch on the camera’s red-eye reducing pre- flash function.

•Turn on the flash unit by the main switch and wait for the flash readiness indicator to light up.
