La photographie des commençants
La photographie des commençants is an 1863 Paris photography manual by Henri de La Blanchère, published by Amyot for beginners in the craft. Its engraved plates show hands-on darkroom and processing work, including labelled apparatus, glass bottles, trays and a man pouring a solution, with letter keys tying each object to the text. A designer could take the clear, diagrammatic style, with its sparse hatching and labelled objects, as a model for technical instructional illustration.
