Traite encyclopedique de photographie
An encyclopaedic photography treatise by Charles Fabre, published in Paris by Gauthier-Villars in 1889 for photographers and technical readers. Its engravings show photographic apparatus: a boxed lens-and-bellows camera on a tripod, a folding bellows extension, and a line diagram of a camera or lens geometry. The hatched line work and plain grey-cream paper give a clear, technical look a designer could borrow for vintage scientific diagrams.
