Photography of artworks in visible light is indispensable for documentation, insurance, sales and other purposes. It is the ID of the work. These images include views of the artwork from all sides.
Images are also taken in raking light to emphasize surface relief, in ultraviolet light to show restorations and fluorescent pigments, and in infrared light to reveal black underdrawing if present.
X-radiography lets us look inside a work of art, reveals concealed restorations and modifications, and sometimes even the presence of another work underneath. This technique also visualizes the physical structure and the state of conservation of the support.
All these photographs are essential tools for the documentation of the technique, signatures, restorations, possible damages, inscriptions, labels, etc.
Scientific images are generally taken prior to our work and help us later on to choose the right places to analyse.
A stereomicroscope is indispensable for any detailed examination and documentation of works of art. For paintings it is used for example to study the canvas fabric, painting techniques and the different paint layers, cracks, signatures and possible fingerprints, as well as for taking microsamples for certain instrumental analysis techniques.
X-Ray Fluorescence spectrometry (XRF)
XRF spectrometry is a non-invasive technique that allows the identification, without contact with the object, of certain inorganic pigments, metals and their alloys, ceramics and glasses, etc. Our instrument is portable and can be taken to the client.
