An introduction to the science & practice of photography
A photography textbook by Henry Chapman Jones, published in London in 1895 by Iliffe, Sons & Sturmey, aimed at students learning the science and practice of the craft. The four pictures are cross-section diagrams of photographic lenses, drawn in hatched outline with a single horizontal axis line marked by arrows showing the path of light through each element. A designer could take from them the clean, schematic style of technical line diagrams, with hatching used to separate glass from air.
