Title: METHOD, TRANSMISSION UNIT, SYSTEM AND COMPUTER PROGRAM FOR WIRELESS COMMUNICATION BETWEEN A CAMERA AND AT LEAST ONE REMOTE FLASH DEVICE
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, andutilized 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 unitssettings 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.
