Abstract

Spectral imaging for radiation wavelengths different from the visible ones, namely in the infrared (IR) and ultraviolet (UV) ranges provides useful information about the actual preservation state and past conditions of paintings. As a consequence, it is possible to combine this information with that obtained in the usual RGB visible basis and to propose digital or 'virtual' restoration of a painting, taking into account its history, modifications and repaintings done in the past. As an example, a work of Pietro Lianori is discussed and analysed.
