However, see Commons:Deletion requests/File:KGerstein.jpg: the drawing can be inspired by the photos or the photos used to get to know the likeness of the subject without the drawing being a derived work. The same also applies to paintings done after photographs, or drawings and paintings done based on other drawings or paintings, and even to drawings or paintings done directly after a 3D sculpture: all are derivative works, and in all cases the copyright of the underlying original needs to be considered.
