According to the U.S. Copyright Office, the owner of the “work” is generally the photographer or, in certain situations, the employer of the photographer. Even if a person hires a photographer to take pictures of a wedding, for example, the photographer will own the copyright in the photographs unless the copyright in the photographs is transferred, in writing and signed by the copyright owner, to another person. The subject of the photograph generally has nothing to do with the ownership of the copyright in the photograph. If the photographer is no longer living, the rights in the photograph are determined by the photographer’s will or passed as personal property by the applicable laws of intestate succession.
