The drawing, in charcoal, watercolor and oil on wood, has been the subject of a 5-year restoration project realized by the Opificio delle Pietre Dure in Florence. The masterpiece was digitalized right after this important restoration project, using a 2+3D gigapixel scanning technique. This allowed every detail to be perfectly reproduced, thanks to an innovative scanning system developed by HALTADEFINIZIONE® with the technical assistance of Memooria.
