Chemical Imaging of Works of Art at the Macro Scale: Chemical Imaging Case Studies: The Complementary Nature of Reflectance and XRF Imaging Spectroscopies

Summary: This symposium, the culmination of a five-year grant by The Andrew W. Mellon Foundation, covers the technological development and implementation of imaging instrumentation, key findings obtained when applied to works of art, and the implications for art history. Scientists, conservators, and art historians document the success of this project and highlight state-of-the-art work occurring at the National Gallery of Art and other institutions around the world using imaging methods based on reflectance spectroscopy in the visible, near-infrared, and mid-infrared, and x-ray fluorescence spectroscopy. Kathryn Dooley, research scientist, National Gallery of Art, Washington, DC, presents several case studies exemplifying the use of reflectance imaging spectroscopy and imaging x-ray fluorescence spectroscopy to the study of paintings and works on paper. Dooley spoke at a one-day symposium held at the National Gallery of Art on September 21, 2015, which was supported by The Andrew W. Mellon Foundation.
