Apport de l'imagerie scientifique à la caractérisation des pigments des œuvres du peintre orientaliste Etienne Dinet

Abstract : This research aims to contribute to the study and characterization of the pigments used by the French painter Étienne Dinet at the dawn of the 20th century. Our approach draws on painting manuals written by the artist (Les fléaux de la peinture), in which he shows his search for materials to be used in painting. Based on these writings, a database of scientific photographs and reflectance spectra (visible and near infrared) was created to determine the pigments used in his paintings. Seven paintings were then studied. Scientific imaging enabled us to characterize the painter’s palette, especially when we had the opportunity to combine several analytical techniques producing complementary data. We have thus shown the value of using a set of non-invasive imaging techniques simultaneously for pigment characterization: no pictorial material is required and the low amount of light radiation during measurements does not affect its conservation. Technical photography can provide a lot of information about the state of preservation of a painting and allows us to detect restoration interventions done over time. It also allows us to make hypotheses about the painter’s palette. To confirm these hypotheses, analyses such as X-ray fluorescence and hyperspectral imaging, which provide more accurate information and more direct interpretation, are required.
