LIGHT-SURFACE INTERACTION IN THE STUDY OF THE RESTORED PAINTINGS

摘要

This paper deals about a new method to restoration old paintings, based on light-surface interaction. Diffuse reflectance spectra can offer information on the electronic absorption spectra of the pigment samples, to be used to reduce the metamerism phenomenon. By mixing modern blue pigments with titanium white it is possible to obtain pigments azurite imitative retouching.
