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:
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.
