In general, copyright belongs to the photographer. The person in the photo might have image/personality rights, depending on the jurisdiction (there's no Berne Convention on image rights) - in the US, the law varies state by state.
Which means that if you're going to have naked pictures taken, it's best to do selfies than having someone take it for you :)
