TTL photographic wireless communication system and method
First Claim
1. A method of synchronizing a remote lighting device to image acquisition of a camera, the camera having a hot shoe connector with a wireless communication device connected thereto, wherein the wireless communication device is not a photographic flash and a photographic flash is not directly connected to the hot shoe connector of the camera, the method comprising:
- receiving a first request for flash data from the camera at the wireless communication device via the hot shoe connector of the camera;
responding to the first request for flash data with response data that mocks information that a photographic flash would provide if the photographic flash 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;
receiving a synchronization signal at the wireless communication device via the hot shoe connector of the camera;
wirelessly communicating TTL information from the wireless communication device to a remote photographic lighting device, the TTL information being based on the TTL data from the camera body;
wirelessly communicating a remote synchronization signal from the wireless communication device to the remote photographic lighting device; and
synchronizing the remote photographic lighting device to an image acquisition by the camera using the remote synchronization signal and the TTL information.

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 flash would provide if the flash 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.

16. A photographic wireless communication device for synchronizing a remote lighting device to image acquisition of a camera having a first hot shoe connector, the device comprising:
-
a second hot shoe connector configured to connect to the first hot shoe connector; a first wireless communication functionality; and a processing element, said processing element and photographic wireless communication device configured to receive one or more data requests from said camera via the second hot shoe connector when the second hot shoe connector is connected to the first hot shoe connector, and to respond to the one or more data requests with response information that mocks information that a flash device would provide if the flash device were connected to the first hot shoe connector instead of said photographic wireless communication device, such that in response to the response information said camera continues to provide TTL data via the first hot shoe to said photographic wireless communication device. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23)
