One-to-One Training at CHSOS studio – April 2019 – Cultural Heritage Science Open Source

Completed 4-days one-to-one Training at the CHSOS Studio in Italy, April 2-5 for Jurian Hoogewerff, University of Camberra, Australia.

Check out our Training Calendar for upcoming events.

Jurian Hoogewerff: forensic geochemist working in Australia. Much of his research and casework is about documenting authenticity of natural materials using elemental and isotope techniques, mostly human remains, soil and food. Recently he has been becoming more involved with art conservation colleagues at the many museums in Canberra wanting to use his forensic equipment, FTIR, pXRF, LIBS, GCMS and other techniques. Jurian has some experience with full spectrum photography and using forensic light sources but now he would really like to learn more about the technical photography of art, especially paintings and indigenous (painted) art.

Jurian has been following CHSOS activities in our newsletter with great interest over the last 2 years, and he was very interested in our 4-day training program. A busy academic he could not participate in one of our organized courses and so he took a one-to-one program which we provide for busy professionals. Thanks for coming and sharing your expertise and point of view as a forensic scientist.

It has been so interesting to discuss with Jurian ( forensic scientist) our methods for Art Examination. We found many points in common. It was fascinating to see an art examination workflow as a crime scene 🙂

FIRST and SECOND DAY: technical Photography

Technical photography represents a collection of images realized with a modified digital camera sensitive to the spectral range (about 360-1100 nm). Different lighting sources and filters are used to acquire a selection of technical images, with each one providing different information about the object under examination.

THIRD DAY: Multispectral Imaging and Reflectance Spectroscopy

Multispectral Imaging is used to identify and map pigments in polychrome artworks, and to enhance the reading of faded historical documents. Conservators can use this technique to distinguish original
sections in paintings and select the proper conservation procedures.

Reflectance spectroscopy (RS) is a powerful portable technique for the identification of pigments.
An RS spectrum shows the ratio between the intensity of the reflected light and the incident light for each wavelength. The RS spectra can provide information useful for pigments identification.
