Dictionnaire de chimie photographique
A French photochemistry dictionary by H. Brauns and Adolphe Braun, published in Paris by Gauthier-Villars in 1904 for photographers and chemists. Its pictures are line diagrams of spectral absorption or sensitivity curves plotted against labelled Fraunhofer lines B through G, with simple black rules on cream paper; a designer might take the clean, schematic graph style and the tidy labelled-axis layout.
