摘要： A system and method for synchronizing a photographic lighting device to image acquisition by a camera using light emission profile information to position a light emission profile at a desired location in an image acquisition window. A light energy balance point of a light emission profile can be used to position the balance point at a desired location in an image acquisition window.

摘要： Photographic lighting devices, systems, and methods having a plurality of electrical energy storage/discharge (EESD) elements and/or one or more light sources in a single photographic lighting device to perform one or more photographic lighting effects. EESD elements and one or more light sources can be configured to have multiple separate light emissions occur in a single image acquisition window. The multiple light emissions are separated in an image acquisition window by a time period that is about shutter speed exposure time/(N−1), where N is the number of light emissions. In one such example, two light emissions are separated by a time period that is about shutter speed exposure time/(N−1).

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.

摘要： A method of synchronizing a remote device to image acquisition by a camera body including detecting a predictor signal of the camera body that occurs a known time prior to shutter opening and using that predictor signal to determine a synchronization time for synchronizing a remote lighting device. Wireless communication is used to synchronize the remote lighting device at the synchronization time. The determining of a synchronization time may occur before or after the wireless communication to the remote lighting device.

摘要： 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.

摘要： A control system for communicating with a controlled device, such as a lighting device, a special effects device and an in-scene device, in a photographic image-acquisition setting using a camera body. The control system is configured to detect a preset pattern of actuation of one or more camera body controls by a user. In response to detecting of the preset pattern, the control system either communicates a power state change signal to the controlled device or causes the camera body to enter into a controlled device control mode that changes the functionality of one or more camera body controls from a camera body functionality to a controlled device control functionality, or both. Such a system can allow a photographer to control a controlled device while remaining at the camera body.
