For the software, see Adobe Illustrator. 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.
Illustration is the art of making images that work with something and add to it without needing direct attention and without distracting from the thing they illustrate. The other thing is the focus of the attention, and the illustration's role is to add personality and character without competing with that other thing.
