Well, I would have thought that when through the palantir, it would show you what you may see (sort of like Galadriel's Mirror), like when Denethor saw the coming of the ships. But is the reason he saw the ships because Aragorn had the palantir with him, so Denethor would not have seen it had the palantir not been with Aragorn? And if so (and I do think so), then when you look into a palantir, can you see a view out of the palantir, as if it were an eye, or does it give you a surrounding view of the area the palantir is in, like an ariel view (which might explain to me why Denethor could see whole fleets of ships)?
