Based on a witness’s basic description—for example, a round face with a big mouth, a receding chin, and a high forehead—a photographic quality face could be created almost magically and then transferred using a video camera to a fourteen-inch TV screen. The witness could then point out differences between the projected image and the face in his or her own memory. The operator could change the distance between various components of the image or swap out individual parts and, in a few minutes, create a new picture for the witness to comment on.
