In the books, Isildur turned invisible by putting on the ring, and dove into a river to escape a band of orcs. The ring, under its own will, slipped from his finger and he was spotted by orcish archers, who killed him.
I’ve always thought that the “invisibility” aspect of the ring was that it shifted the wearer into the shadow realm. The Nine were invisible without their cloaks, but were visible when the ring was worn. It also made the wearer more visible to Sauron, iirc.
If that’s the case, then the power granted by the ring might mean that magic users (such as Gandalf or Galadriel) would more easily draw on power from the other realm into this one.
