I live near to a large road, far enough away so it doesn't keep me awake There is a pedestrian bridge that goes over the road and provides an interesting view. I think it might look good at night with a long exposure to capture moving traffic. I have never really done this before and whilst I am prepared to do a bit of trial and error is thee any basic advice I should take into consideration before I head down? Shooting mode? Metering mode? WB? Any help much appreciated.
