The copyright issues will vary between jurisdictions - e.g., in Canada, unless modified by contract, the copyright will initially vest in the party hiring the photographer, whereas in the USA, unless modified by contract, the copyright will initially vest in the photographer.

And in either jurisdiction, the copyright in the image is separate from the negatives themselves.

Simple, it is not!
