Illustration consist of drawings, either hand or computer-generated. Illustration offer far more opportunities for interpretation than photos do. The artist can selectively organized and emphasize information. Therefore, artwork can convey both accuracy and atmosphere or substitute accuracy for aesthetics. For example, a draw-type program can be used to render an image of a person’s hand, either literary or abstractly. In this age of computer graphics, cutaways (line diagram) of objects are often used in technical manuals and documents. These illustration can show the structure of an object with more clarity than photographs of the various components of the object.
