Hello! So I know that the shorter the flash duration of a flash unit is, the less motion blur will be introduced into an image of a fast moving subject. But if the flash duration was really long, longer than the sync speed of the camera (1/250), would it be possible to sync at higher shutter speeds? My understanding of how faster shutter speeds are obtained is that the curtains move at the same speed, 1/250, but they create a progressively narrower moving slit to expose the sensor to less light as you increase the shutter speed. So if a 1/8000 shutter speed was still moving the curtains for 1/250 of a second, that would mean that if the flash duration was also that slow, it would be lighting up the scene for the entire duration of the exposure. Is this a fair assumption to make? I'm sure the intensity of the flash would change over the course of the exposure, but it seems to me that you could potentially get a reasonably acceptable image this way. Any thoughts?
