Reflectance imaging spectroscopy used to map minerals both on Earth and on Mars is being adapted through the development of high sensitivity portable spectral cameras and analysis tools to assist in the mapping and identification of artist materials in situ. The same methods are being used to give detailed images of preparatory sketches and prior painting compositions in old master paintings.
