My interest in medical presentations dates back to my post-graduate training in orthopaedics in the late 1960s. Making a slide was an elaborate process: once the text for a slide was finalized, a medical artist prepared an art work. After the author had edited, artwork was photographed. Slides were classified as positive—black image on white background; negative—white image on black background; diazochrome white image on blue background; and true colour slides. Black and white slides were easiest to procure. Further processing with diazo dyes produced classic blue background and text appearing in white. The colour transparency films were expensive and were used for special lectures. All slides were mounted in a frame and placed sequentially in a special carrier box for projection. Upside down projections were common. The number of slides used was limited. In the early 1980s, I organized a symposium on medical slides with the help of my friend Rajeshwar Singh who owned a medical advertisement studio. In one of the talks, I declared, ‘there are seven ways of projecting a slide wrongly and only one correct method’. Over the years, I accumulated considerable information on presentation skills and gave several seminars on the subject.
