TTL photographic wireless communication system and method with exposure compensation value transfer to a remote lighting device |
摘要 |
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. |

1. A method of synchronizing a remote lighting device to image acquisition of a camera, the camera having a hot shoe connector with an external device capable of wireless communication connected to the hot shoe connector, the external device including a radio frequency transmitter for wireless communication, the method comprising:
communicating a first information from the external device to the camera via the hot shoe connector of the camera, the first information mocking information that a flash device would provide to the camera if the flash device were connected to the hot shoe connector of the camera, wherein the external device is not a flash device; receiving a TTL data at the external device capable of wireless communication, said receiving a TTL data occurring via the hot shoe connector of the camera; receiving a synchronization signal at the external device via the hot shoe connector of the camera; wirelessly communicating an exposure compensation value from the external device to a remote lighting device using the radio frequency transmitter; and wirelessly communicating using the radio frequency transmitter a remote synchronization from the external device to the remote lighting device for synchronizing the remote lighting device to an image acquisition by the camera using the remote synchronization signal. |
