Nashville is a beautiful town, and at blue hour with all the lights - perfect!
I go to Nashville several times per year, and always look forward to it. It's a beautiful town, and I have had more than my share of good luck while shooting there. Things just always seem to work out, for some reason.
One other thing I like about Nashville is the size of the city. It's not that big (at least the core downtown area) so it's pretty easy to get around and shoot all the stuff you want to shoot while you are down there. It's a pretty easy walk from one spot to the next.
And...that comes in handy when sunset and blue hour start happening. There is nothing worse than watching great light disappear while you are trying to get in to position for some shots.
I was there not too long ago, and got out to shoot one evening with my friend Mark. We hit quite a few spots all the way through blue hour, and then it started raining. See? It just works out! (click any photo to enlarge)
