Practical color photography
Practical color photography is a 1922 technical manual by the English photographer Edward John Wall, published in Boston by the American Photographic Publishing Co. for amateur and professional photographers working in color. Its pictures are simple black-and-white line diagrams and tonal figures, such as a perspective drawing of a stepped solid, a hand-drawn cutaway with lettered corners, and a graph-paper chart of densities; a designer could borrow their crisp geometric construction, clear lettering and sparse monochrome contrast for diagrammatic layouts.
