      6. <skos:note xml:lang="en">Infrared reflectography is a digital imaging technique that allows study of layers beneath the surface of a painting by capturing absorption/emission characteristics of reflected infrared radiation. A complementary technique to x-radiography, IRR uncovers somewhat different information.The longer wavelengths of infrared radiation penetrate most surface pigments and reveal charcoal or graphite underdrawings, the underlying initial stages of a composition.</skos:note>
