Case Study 1: Portrait of a Young Woman: Assessing New Technologies
摘要
This case study evaluates the respective use of five non-destructive techniques that are at our disposal to research the characteristic style and painting technique of Frans Hals. For this purpose, a typical Frans Hals portrait of around 1635, Portrait of a Woman in the Gemäldegalerie in Berlin, was researched using not only observations with the naked eye, x-rays (XR) and infrared reflectography (IRR), but also macro-x-ray fluorescence scans (MA-XRF), hyperspectral imaging also known as reflectance imaging spectroscopy (HI/RIS), and even neutron activated radiographs (NAR). As the portrait is the only painting to date to have been researched with all these techniques, it provided a unique opportunity to compare their respective merits and assess their potential.
