The CRISATEL system is dedicated to fine art painting digitalization. A specific calibration procedure has been defined and implemented for this system. Some existing spectral reflectance reconstruction methods have been tested and compared. A multispectral image of a Georges de la Tour painting, “Saint Jacques le mineur”, has been processed.
