Technical Illustration and the Video Camera 
A video camera is an excellent tool for preparing technical illustrations and procedures. A video tape of a procedure provides chronological information. It provides visual images that can be used as the basis for technical illustrations. Visual images and details are recorded permenantly so that they are not forgotten. The research information can be passed on to another author. A case study illustrates how a video tape can be used to document a procedure and produce electronic illustrations.
