Realistic line drawings--a simple technique

Medical teachers usually do not have ready access to a resource for obtaining good quality illustrations for routine instructional activities and, at times, even for presentation of research findings in publications or at seminars. The inadequacy is especially apparent when human figures or objects need to be shown indicating depth of vision and relative sizes of the parts accurately. Tracings of the relevant features made from photographic prints result in very satisfactory illustrations. The technique can be used by the average teacher and is not time consuming.
