Metz 28 AF-4 N Flash synchronisation, Normal synchronisation, Slow-synchronisation

6. Flash synchronisation

Different modes of flash synchronisation are possi- ble, 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 synchronisation, switching to the camera’s flash sync shutter speed is automatic. The shutter speed

kmay 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

Some cameras feature specific exposure programs for slow-synchronisation.

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 back- ground. 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 operating instructions for further details.
