Abstract

Here we apply the Retinex tool of GIMP software, for filtering the digital images of the masterpieces of an artist that used the Chiaroscuro, a strong tonal contrast between light and dark, in his painting technique. In particular, we use the GIMP Retinex for some works of Gerrit van Honthorst, known in Italy as Gherardo delle Notti. The filter allows the vision of significant details in the shadows of the images.
