In 1866 the Duke de Luynes travelled through North Africa for the purpose of inspecting and bringing back visual records of the region's major antiquities and historic sites. Accompanying him were the photographers Louis Vignes and Henri Sauvaire. They required a medium that was adaptable to the heat, unbreakable and light enough for their lengthy travel itinerary. They chose calotype paper negatives.For more information on Sauvaire, see: Perez, Focus East, pp.216-217, and Brettell, et. al., Paper and Light: The Calotype in France and Great Britain, 1839-1870, pp.182-183.
