Cultural detective work: Remote hyperspectral imaging in the mid-infrared region enables the identification and localization of the painting materials used by artists (see brightness temperature difference image overlayed with the corresponding portion of the painting Sestante 10 by Alberto Burri and IR reflection spectra for this area). The resulting molecular images are thus of great value for art conservation.
