Ok, so something I'm confused about. Since I can't see it in the specs. When you're shooting with the B1, how does the camera/flash know how far away from the subject it is, AND how does it know how much light the modifier is sucking out of it? Seems like plug and play, so there's a pre-flash coming from the B1 for every shot you take?
OR am I missing something?
