Lower left: False-color infrared reflectance image (blue - 1000 nm, green - 1350 nm, red - 1650 nm) reveals underdrawing lines that denote the smaller hindquarters of the initial Lamb. Lower right: Map derived from processing the infrared reflectance image cube showing the initial Lamb with a slightly sagging back, more rounded hindquarters and a smaller tail. Brighter areas of the map indicate stronger absorption from the -OH group associated with one of the forms of lead white.
