Hello Frank,
you can also see it with Johann, Rüdiger and me, as well as with some others. However, all images are protected by copyright, whether with or without the copyright sign. The well-known © copyright sign does not exist in German copyright either, it comes from Anglo-American copyright. A copyright sign can at most serve to facilitate evidence when a lawsuit is about the question of whether the picture was actually taken by the photographer. If you create images and want to prevent them from being spread wildly on the Internet, you should watermark them. However, this is only for provability. Copyright protection arises with the creation of the photo.
