I understand flash sync speed - in that the focal plane shutter moves so that over a certain speed the curtain moves together as a slit, hence seeing a black bar if you go over the sync speed. However given that the flash itself has a certain duration, lets say 1/1000th of a second, what will happen if I shoot a 1/2000th of a second. Surely the duration of the flash exceeds the exposure so the slit would move whilst the flash is active so I would get a properly exposed photo?
I'm sure that can't be that simple otherwise I would have heard about it. What made me think is that canon has a high speed sync mode and I was wondering how the did it - just a long flash duratation or a series of very close flashes?
