CHSOS collaborated with Catania (Sicily) Archaeological authorities to contribute Technical Photography Diagnostics on the newly discovered XII century wall paintings in Nunziatella di Mascali, Sicily. CHSOS studied them with high resolution Visible, Infrared and Infrared False Color photography. We contributed “Indagine diagnostica multispettrale sugli affreschi” to the just published “La Nunziatella sopra Mascali”.
