That's correct. And yet you still see U.S. museums trying to act as if they own coipyrights on all the art in the museum, so that people who don't know better end up paying them royalties they don't need to.

The case was Bridgeman v. Corel. Unfortunately, it only applies in the U.S., and while the reasoning behind it is sound, and should apply elsewhere, Europeans have a different take on copyrights in general than the U.S. does.

The last time I was at the Louvre, they did allow still photography as long as a flash is not used. Many museums allow this. But they typically also forbid tripods on the grounds that they might impede traffic. Most museums forbid videotaping (not sure of the rationale there), and every museum I've been to in Italy forbids all photography.
