The directors camera has a much greater capability to be positioned/more controls. However it is invisible in the scene. I use the directors to set up my shot, play around with the visual composition, etc. I then set the camera to the same as the director. This way i can always find my way back even if I am not happy with my altered view and have not saved in one of the buttons. You can render from either. Itis all illusion. Treat it like a movie set. Scale is not mandatory but the illusion of it is. Have fun and play!

Pass no temptation lightly by, for one never knows when it may pass again!
