national archives Technical Photography MSI

Just delivered on October 10th 2019 a complete Technical Photography and Multispectral Imaging system for the National Archive in The Hague, The Netherlands.

We delivered, installed and tested a Technical Photography kit and a Multispectral Imaging System “Antonello“. Libraries, Historical Archives, and paper conservators are more and more interested to apply these diagnostics tools to their collections.

Do you need these methods also in your Institution?

CHSOS serves an international audience of institutions and art professionals such as conservators, art historians, art appraisers, fine art photographers, and conservation scientists. Its technical innovations and strategies are being adopted by museums and cultural institutions worldwide. CHSOS disseminates this knowledge through the CHSOS website, publications, and training programs.

  • Our Training programs teach practical methods for Art Examination and Documentation. Our modules illustrate imaging and spectroscopy methods regularly used by cultural heritage scientists and conservators for the scientific and forensic investigation of art objects.
  • All the training modules have hands-on activities and students practice with our CHSOS equipment. No need for you to bring any equipment.
  • No specific educational background is necessary. Our courses are designed for a large audience ranging from art professionals to scientists.

Technical Photography (TP) kit

We offer a complete kit for Technical photography (TP) which includes a full spectrum camera sensitive from the Ultraviolet to the Infrared radiation and the set of necessary filters and lamps. Our TP kit represents a good compromise among quality, adaptability, and costs. It allows to realize a complete set of 8 technical photo documentation methods: VIS (visible photography), UVF (Ultraviolet Fluorescence photography), UVR (Reflected Ultraviolet photography), IR (Infrared photography), IRF (Infrared Fluorescence photography), IRFC (Infrared False Color photography), IRT (Infrared Transmitted photography) and RAK (Raking light photography).


This kit is recommended for art professionals such as conservators, art appraisers, archaeologists, art historians. Use it for a fast and informative examination of easel paintings, wall paintings, manuscripts, and historical documents.

Multispectral Imaging (MSI) system

Conservators and art historians need non-invasive methodologies to identify and map pigments on works of art and archaeology. These tools allow them to select appropriate conservation procedures, acquire information on the workshop practices, distinguish original sections from inpaints and to enhance visualization of faded pigments and inks.

Antonello is our simple MSI system composed of 18 bandpass filters and a digital camera, covering the 400-925 nm spectral range. Using a digital camera rather than a monochromatic scientific dedicated camera has the advantage that the same camera can be used for other technical photographic methods, making the overall imaging equipment lighter, compact and affordable.

We developed Antonello to spread the use of this methodology across Art Conservation professionals and institutions. Antonello, our low-cost MSI system for Art and Archaeology uses specifically designed in-scene gray reference targets and it is versatile and adaptable to the specific needs of different art or archaeology examination projects, such as manuscripts, wall paintings, and easel paintings.

We developed Antonello to be: user-friendly, compact and lightweight, easy to understand, tune-up and upgrade.
