Abstract
A system and method for synchronizing a remote lighting device to a camera using a hot shoe connection and a wireless communication device connected via the hot shoe connector. The wireless communication device receives a request for flash data from the camera via the hot shoe connector. The wireless communication device responds to the request with response data that mocks information that a photographic lighting device would provide if the photographic lighting device were connected to the hot shoe connector, such that the camera continues to provide TTL data via the hot shoe connector to the wireless communication device.
