A flash generator is capable of identifying which type of flash head and flash head extension cables that is connected to the flash generator. A flash head and flash head extension cable can be identified by the flash generator. The flash generator provides a power supply to a flash head. Further the flash generator includes a first current generator for charging the capacitor. The flash generator further includes a second current generator or a voltage generator connected to an output of the flash generator and arranged to provide a current or a voltage to create a voltage U.sub.ID over a component in a flash head or a flash head extension cable connected to the flash generator. Processing means are arranged to identify the flash head or the flash head extension cable by the measured voltage U.sub.ID.

An LED fixture is provided for photographic and theatrical lighting. The light fixture is particularly suitable for photographic and theatrical lighting by mounting LED elements directly or indirectly on articulating arms. The arms have a first pivot mounted segment connected by a hinge to a hub and a second pivot mounted segment connected by an intermediate hinge to said first pivot mounted segment.

There is provided a control device, a control method, and a program through which it is possible to implement a more suitable imaging environment even under a situation in which auxiliary light is emitted from a plurality of light sources, the control device including: an acquisition unit configured to acquire a light emission state of a first light source; and a control unit configured to control an operation of light emission of a second light source that is different from the first light source according to the acquired light emission state of the first light source.

The present invention generally relates to the field of communication between electronic devices used for photography. In particular, the invention relates to a method, transmission unit, system and computer program for wireless communication between a camera and at least one remote flash device, such as photoflash units and related equipment.
