I live in France near Paris, and there a lot of nice locations I can be at in less than an hour, but one of the big problems is that for a lot of them, you need a special authorization to shoot. For example it is close to impossible to do a shoot within the Versailles castle, even for historical costumes.
The most beautiful place I've shot at is probably Chambord castle, and I only got to shoot there because we were the official photogs of an historical costume event :
Inside Paris is a nightmare if you want to shoot inside buildings, fortunately you can shoot in the street with a small team without being bothered by anyone. I did a very nice shoot in the Saint-Michel/Notre Dame area :
In my experience, the further from Paris, the easier it is to get to shoot in beautiful locations. Paris is simply too crowded with tourists.
