Quality is seen as a primitive characteristic of media, but one that can be manipulated in various ways. Since media vary in their "relating power," that is, their ability to involve students, standards of quality also may vary in the ways certain production technique parameters, such as lighting, sound, and exposure, are manipulated. Some media, such as video, are seen as having great relating power, and yet these require careful technique in order to keep the medium's inherent characteristics from generating unintended "messages," which in many cases become distracting noise. Specific techniques for maintaining high quality and, thereby, high effectiveness in the media of video, audio, and photographic slides and prints are discussed. (Author/CFM)
