The optics of photography and photographic lenses
A 1904 London and New York technical treatise by J. Traill Taylor and P. F. Everitt, written for photographers and optical workers to explain how photographic lenses are designed and how light passes through them. The pictures are plain line diagrams of lens cross-sections, drawn as hatched glass elements with horizontal ray lines and an aperture stop between paired groups, showing how a designer could visualise optical arrangements as simple geometric shapes.
