I'm looking for advice on photography etiquette when photographing old buildings. Neglected barns, abandoned stores, old churches and such. Even though they are abandoned, they still belong to someone, and we shouldn't trespass. But, is it ok to shoot them from the road or right-of-way? Or maybe we should always go chat up the closest neighbors, give them one of our cards (a good reason for even amateur photographers to get business cards!) and ask about taking a photo or two?
It probably also depends on regional customs; here in more rural parts of the South (USA), I would definitely not go wandering off where I don’t know anyone, yet in the suburbs and urban areas, there is more leeway. Any knowledge appreciated!
