This book shows how different diascopic illumination methods influence what a viewer sees. A number of specimens are seen using dark field, bright field, oblique, polarized, monochrome, and Rheinberg illuminations. A Diabloc (R) digital multifilter is used to select each method with the click of a mouse. The paperback edition includes a flip-book section that shows time-lapse images of the crystallization of caffeine.
