In legal discourse, an author is the creator of an original work, whether that work is in written, graphic, or recorded medium. The creation of such a work is an act of authorship. Thus, a sculptor, painter, or composer, is an author of their respective sculptures, paintings, or compositions, even though in common parlance, an author is often thought of as the writer of a book, article, play, or other written work.In the case of a work for hire, the employer or commissioning party is considered the author of the work, even if they did not write or otherwise create the work, but merely instructed another individual to do so.

Drawing is a visual art that uses an instrument to mark paper or another two-dimensional surface. The instrument might be pencils, crayons, pens with inks, brushes with paints, or combinations of these, and in more modern times, computer styluses with graphics tablets.

Painting is a visual art, which is characterized by the practice of applying paint, pigment, color or other medium to a solid surface  The medium is commonly applied to the base with a brush, but other implements, such as knives, sponges, and airbrushes, may be used. One who produces paintings is called a painter.

An illustrator is an artist who specializes in enhancing writing or elucidating concepts by providing a visual representation that corresponds to the content of the associated text or idea. The illustration may be intended to clarify complicated concepts or objects that are difficult to describe textually, which is the reason illustrations are often found in children's books.
