speeds. If you need the full light output

of the flash unit, you should not select a

shutter speed that is any faster than

1/125 sec.

10.2 Normal synchronisation

In normal synchronisation the flash unit

is triggered at the beginning of the shut-

ter time (first curtain synchronisation).

Normal synchronisation is the standard

mode on all cameras. It is suitable for

most flash shots. The camera, depending

on the mode being used, is switched to

the flash sync speed. Speeds between

1/30 sec. and 1/125 sec. are customa-

ry (see the camera’s operating instruc-

tions).

No settings are necessary on the flash

unit, nor is there any display for this

mode.

10.3 Second curtain synchronisa-

tion (REAR)

Some cameras offer the option of

second-curtain synchronisation (REAR),

in which the flash unit is not triggered

until the end of the exposure time.

This is particularly advantageous when

used with lower shutter speeds (slower

than 1/30 sec.) and moving subjects

that have their own source of light. With

second-curtain synchronisation, a

moving light source will trail a light stre-

ak instead of building one up ahead

itself, as it does when the flash is syn-

chronised with the first shutter curtain. In

this way a „more natural“ image of the

photographic situation is produced!

Depending on its operating mode, the

camera sets shutter speeds slower than

its sync speed.

On some cameras the REAR function is

not possible in certain operating modes

(e.g., certain vari- or subject programs,

or with red eye reduction). In these

cases, the REAR mode cannot be selec-

ted and/or is automatically cancelled or

ignored (see camera’s operating instruc-

tions).
