Traité général de photographie
Traité général de photographie is a French technical manual by Désiré van Monckhoven, published in Paris by G. Masson in 1880 for photographers and students of the craft. Its pictures are precise black-and-white line engravings of cameras, stands, and lens assemblies, drawn with lettered reference marks; a designer could take their clean hatching and exploded-view layout as a model for technical diagrams.
