Over the course of the last 2.5 years Rembrandt’s Night Watch has been investigated with the most advanced research methods, computational and visualisation technologies. This Operation Night Watch symposium will focus on the technological innovations and scientific results.

The symposium will present innovative approaches, research challenges, new insights and breakthroughs in our understanding of the use of materials, the composition of the paint and build-up and the condition of the painting. The research has been performed from the macro-to the nanoscale, in a non-invasive manner combined with micro-sampling. A wide range of scientific topics will be covered, including colour, chemical composition, degradation, texture, structural canvas analyses, cleaning studies, data fusion, visualisation tools and artificial intelligence.


The speakers will be present in the live broadcast to answer your questions and discuss.
