Thanks to the high reflectance of azurite in the SWIR range, this image most clearly reveals the presence of an angel hovering above Joseph’s head, which was sketched but never painted.

Several pentimenti are hidden beneath the paint layers on this page; in some cases, they can be perceived with the naked eye, through the light blue azurite used in the sky. They are more easily seen in the near-infrared image and become even clearer in the images recorded using infrared reflectography (hotspots 1 and 2).
