12 Synchronisation on the

1st or 2nd shutter

curtain (REAR)

Some cameras support synchronisa-

tion with the 2nd shutter curtain

(REAR). Thus, the flash unit is not fired

until the shutter has closed. This is

especially advantageous when ligh-

ting with slow shutter speeds (>

1/30s) and moving objects with their

own light sources since moving light

sources leave behind a trail of light,

instead of in the front as with synchro-

nisation on the 1st shutter curtain. This

results in a more “natural” reproduc-

tion of the situation when the picture

was taken for moving light sources.

Depending on the operating mode,

the camera triggers slower shutter

speeds than the flash sync speed.

In some cameras, in certain operating

modes (e.g. with certain Vari and/or

Object programs or with pre-flash

function against the “red-eye effect”),

REAR operating mode is not possible.

The REAR operating mode cannot be

selected in this case or is automatical-

ly deleted or not performed (see

Camera user manual). The REAR ope-

rating mode is set on the camera (see

Camera user manual). No settings are

necessary on the flash unit, nor is the-

re any display for this mode.

13 Slow synchronisation

(SLOW)

SLOW lighting brings the picture

background into stronger focus with

weak ambient lighting. This is achie-

ved by the camera shutter speeds that

are adjusted to the ambient light.

Thus, automatic shutter speeds are

automatically triggered that are lon-

ger than the flash sync speed (e.g.

shutter speeds up to 30s). Slow syn-

chronisation is activated automatically

on some camera models in connection

with certain camera programs (e.g., a

night shot program, etc.), or it can be

set on the camera (see the camera’s

operating instructions). No settings

are necessary on the flash unit, nor is

there any display for this mode.
