Abstract:
A system and method for synchronizing a remote lighting device to a camera using a hot shoe connection and an external device connected via the hot shoe connector. The external device receives TTL data and a synchronization signal from the camera via the hot shoe connector. The external device wirelessly communicates using a radio frequency transmitter an exposure compensation value from the external device to a remote lighting device. The external device also wirelessly communicates a synchronization signal and a TTL information to the remote lighting device for use in synchronizing the remote lighting device to image acquisition by the camera.
