Utilizing Original TEM Negatives and Micrographs For Teaching in the Digital Domain

Abstract Original transmission electron micrographs illustrating a variety of biological tissues are excellent tools that can be used in the education and examination of first year medical students. Many of these valued micrographs (and the negatives that produced them) date back to the 1960s, to the time when this researcher started a career in microscopy that continues to this day, To avoid returning to the darkroom and laborious photographic techniques, original negatives were scanned to produce micrographs for use in written or laboratory examinations or as images transported into Power Point lecture presentations. Original micrographs also were scanned and provided additional educational materials.
