    Abstract: 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. More in particular, the invention provides a way of controlling a plurality of flash devices from an intermediate radio transmission unit mountable on the camera, and utilized a delay a sequence flash control sequence so as to synchronize the function of the camera and the remote flash devices during image acquisition. Further the invention provides a way of controlling in the photoflash units settings for the main flash, wherein the setting are the last settings determined by the camera when the intermediate radio transmission unit was in a TTL-mode.

    Abstract: The present disclosure relates to a flash generator for providing power supply to a flash tube so that the flash tube rapidly provides a light output adapted to FP-sync, Flat Peak. The flash generator comprises a capacitor bank, an output and a switch configured to switch a current flow from the capacitor bank via the output to provide a variable power via the output. The flash generator further comprises a controller for controlling the switch, whereby by controlling the on time of the switch, the generator is operative to provide, during a time period of 100 to 2000 μs during a peak time period within the time period, an average power at least 4 times higher than the average power provided during the other time period within the time period, whereby the flash tube during the peak time period becomes fully ignited.

    Abstract: A generator for a flash device includes at least a first capacitor bank, which includes at least one capacitor of a first type and at least a second capacitor bank, which includes at least one capacitor of a second type. The first capacitor bank is connectable to a charger via a first switch and the second capacitor bank is connectable to a charger via a second switch. The generator is configured to individually control the first switch and the second switch so that the first capacitor bank and the second capacitor bank can be individually charged to the same or different voltages. Since the first capacitor bank and the second capacitor bank can be simultaneously discharged, it is possible to achieve a desired energy level and color temperature from a flash device connected to the generator.
