The European Parliament is voting on whether to remove the Freedom of Panorama in Europe. When there’s Freedom of Panorama, you can take photographs if you’re on public ground and then do more or less what you want with them: publish them, sell them… When there’s no Freedom of Panorama, you can’t. You’d have to get permission from whoever holds the rights to the buildings that would appear in the photograph, which would be impossible in general.
This is bad for people who just want to take nice photos, but it’s also a bad thing for all of us. If we can’t take photographs of, say, police behaving badly, then we don’t really have any freedom at all.
There’s a petition.
