Excerpt:Â The Sketch Effect: An artist sketches a young subject. During the session, the artist engages in conversation with the subject, observes the subject's mannerisms, and develops a sense of the subject's personality. The finished work not only encompasses the physical exactness of the subject, but includes the artist's incorporation of the subject's characteristics as well. The original sketch is passed along to another artist to be duplicated. The second artist renders a final sketch based upon the first sketch, but, without being witness to the characteristics of the original subject, projects their depiction of the subject's personality into the sketch. This process is repeated until the tenth artist completes their sketch. When the original sketch is compared to the tenth sketch, the similarities are vague and the tenth sketch has taken on the aura of a caricature of the first sketch. Yet when the tenth artist is asked to sketch the original subject under the same circumstances as the first artist, without knowledge of who the subject is, the sketch completed by the tenth artist of the original subject only has a vague similarity to the tenth artist's original sketch.
