Normal Synchronisation; End Of Exposure Synchronization - Leica SF 58 Instruction Manual

Normal synchronization
With normal synchronization, the LEICA SF 58 is fired at the beginning of the
exposure , that is, immediately after the shutter opens. This synchronization is
the standard mode and is carried out on all cameras. It is suitable for most
flash shots.
The camera, depending on the illumination mode set, is switched to the flash
sync speed.
There is no setting or display on the flash unit for this mode.
Note:
Following the focal plane shutters with their two curtains used in the majority
of system cameras, in particular system cameras, this synchronization is usual-
ly called "with the first curtain."
However, in the case of the between-the-lens shutters used in most compact
cameras and some interchangeable lenses, this designation is incorrect. Con-
sequently, in this manual, the synchronization of the exposure applicable in
both cases is mentioned in the beginning or at the end, see section below.

End of exposure synchronization

Several cameras offer the feature of synchronization with the end of the expo-
sure (usually termed "second curtain synchronization"). This is particularly
advantageous when used with slow shutter speeds (>1/30 s) and moving sub-
jects that have their own source of light or that reflect light. With second cur-
tain synchronization, a moving light source will "trail a light streak" instead of
"building one up ahead of itself", as it does when the flash is synchronized
with the beginning of the exposure. This produces a „more natural" image of
the photographic situation in the case of moving light sources.
The synchronization with the end of the exposure is set on the camera (see the
camera's instr.)! Depending on the exposure mode set, the camera then sets
shutter speeds slower than its sync speed, especially in the case of darker sub-
jects.
Note:
Use a tripod when shooting with slow shutter speeds to avoid blurred images!
