The article discusses the chromatic changes in paintings by Adriano de Sousa Lopes following the removal of aged varnish. The study focuses on the impact of varnish removal on spectral reflectance and the effectiveness of different cleaning methods. It highlights the importance of considering individual varnish layers to minimise errors in the analysis.
The research compares the spectral reflectance of paintings before and after varnish removal, emphasising the need for accurate digital restoration methods. Various solubility tests were conducted to determine suitable cleaning solutions for different coloured areas, with the aim of preserving the original painting while removing the oxidised varnish layer.
The study also explores the limitations of traditional colour space analysis and the value of using chromatic descriptors to assess changes in discernible colours and colour gamut. The article concludes that further modelling and analysis are necessary to improve the accuracy of digital restoration techniques and to better understand the optical effects of varnish removal on artistic paintings.
Overall, the research provides insights into the complexities of varnish removal and the importance of precise spectral analysis in conservation and restoration interventions for preserving the integrity of artistic works.
