In the early 1850s Nègre began working on a photogravure process based on earlier experiments by Niepce de Saint Victor. By 1855 he had perfected it and was awarded a first class medal at the Paris Exposition Universelle of that year for his photogravures. As a result Jean Baptiste Lassus, chief architect for the restoration of Chartres Cathedral succeeded in having the French government commission Nègre to create two large photogravure plates of Chartres. Eventually he made three which were published in the Monographie de la Cathédrale de Chartres in 1867.
