6. Flash synchronisation
30
Different modes of flash synchronisation are possible,
depending on the camera model. Please refer to the
camera’s operating instructions to find out how the
individual modes of synchronisation are set on the
camera.
6.1 Normal synchronisation
This mode is available with all TTL cameras, and it is
suitable for most flash shots. With normal synchroni-
sation, switching to the camera’s flash sync shutter
speed is automatic. The shutter speed may vary from
1/30th and 1/250th seconds, depending on the
camera model. Please refer to the camera’s
operating instructions for further details.
6.2 Slow-synchronisation
Various cameras feature a slow-sync function in the
program and aperture priority modes. Flash shots at
low lighting levels and fast shutter speeds (normal
flash sync speed) can often result in overexposed
subjects in front of a very dark background.
The slow-sync function allows the use of slow
shutter speeds right up to 30 seconds, to significantly
enhance the background as a result of the extra
ambient light. Such shots require a tripod to prevent
camera shake. Please refer to the camera’s opera-
ting instructions for further details.
