I'm completely new to "wireless" flash and I must admit I assumed that this meant something like WiFi, i.e. radio controlled. However, it seems I'm wrong and when Canon talk about wireless flash control, they actually mean slave flash, controlled optically by the inbuilt flash and that therefore the sensor on the external flash actually has to be able to "see" the light from the inbuilt flash. I have a Yongnuo 568EX II flashgun and all I want to do is to have it on a bracket which lifts it well up above the camera. I have the bracket but have failed to get the Yongnuo to fire in this position, presumably as it's facing the same way as the inbuilt flash. Everything works OK when the inbuilt flash light can reach the Yongnuo sensor. In any case, I ideally want only the external flash to fire, not the inbuilt one.
Am I right to assume that the only choices I have are to get either an old fashioned off camera cord or one of the Yongnuo radio control units?
