On 8 July 2019 the Rijksmuseum starts Operation Night Watch. It will be the biggest and most wide-ranging research and conservation project in the history of Rembrandt’s masterpiece. The goal of Operation Night Watch is the long-term preservation of the painting. The entire operation will take place in a specially designed glass chamber so the visiting public can watch.
Never before has such a wide-ranging and thorough investigation been made of the condition of The Night Watch. The latest and most advanced research techniques will be used, ranging from digital imaging and scientific and technical research, to computer science and artificial intelligence. The research will lead to a better understanding of the painting’s original appearance and current state, and provide insight into the many changes that The Night Watch has undergone over the course of the last four centuries. The outcome of the research will be a treatment plan that will form the basis for the restoration of the painting.
Operation Night Watch can also be followed online from 8 July 2019 at rijksmuseum.nl/nightwatch
Operation Night Watch will look at questions regarding the original commission, Rembrandt’s materials and painting technique, the impact of previous treatments and later interventions, as well as the ageing, degradation and future of the painting. This will involve the newest and most advanced research methods and technologies, including art historical and archival research, scientific and technical research, computer science and artificial intelligence.
During the research phase The Night Watch will be unframed and placed on a specially designed easel. Two platform lifts will make it possible to study the entire canvas, which measures 379.5 cm in height and 454.5 cm in width.
Researchers will make use of high resolution photography, as well as a variety of advanced imaging techniques, such as macro X-ray fluorescence scanning (macro-XRF) and hyperspectral imaging, also called infrared reflectance imaging spectroscopy (RIS), to accurately determine the condition of the painting.
The Night Watch will be scanned millimetre by millimetre using a macro X-ray fluorescence scanner (macro-XRF scanner). This instrument uses X-rays to analyse the different chemical elements in the paint, such as calcium, iron, potassium and cobalt. From the resulting distribution maps of the various chemical elements in the paint it is possible to determine which pigments were used. The macro-XRF scans can also reveal underlying changes in the composition, offering insights into Rembrandt's painting process. To scan the entire surface of the The Night Watch it will be necesary to make 56 scans, each one of which will take 24 hours.
A total of some 12,500 photographs will be taken at extremely high resolution, from 180 to 5 micrometres, or a thousandth of a millimetre. Never before has such a large painting been photographed at such high resolution. In this way it will be possible to see details such as pigment particles that normally would be invisible to the naked eye. The cameras and lamps will be attached to a dynamic imaging frame designed specifically for this purpose.
Operation Night Watch is for everyone to follow and will take place in full view of the visiting public in an ultra-transparent glass chamber designed by the French architect Jean Michel Wilmotte.
The Rijksmuseum has extensive experience and expertise in the investigation and treatment of paintings by Rembrandt. The conservation treatment of Rembrandt’s portraits of Marten Soolmans and Oopjen Coppit was completed in 2018. The research team working on The Night Watch is made up of more than 20 Rijksmuseum scientists, conservators, curators and photographers. For this research, the Rijksmuseum is also collaborating with museums and universities in the Netherlands and abroad, including the Dutch Cultural Heritage Agency (RCE), Delft University of Technology (TU Delft), the University of Amsterdam (UvA), Amsterdam University Medical Centre (AUMC), University of Antwerp (UA) and National Gallery of Art, Washington DC.
Rembrandt’s Night Watch is one of the world’s most famous works of art. The painting is the property of the City of Amsterdam, and it is the heart of Amsterdam’s Rijksmuseum, where it is admired by more than two million visitors each year. The Night Watch is the Netherland’s foremost national artistic showpiece, and a must-see for tourists.
Rembrandt’s group portrait of officers and other civic guardsmen of District 2 in Amsterdam under the command of Captain Frans Banninck Cocq and Lieutenant Willem van Ruytenburch has been known since the 18th century as simply The Night Watch. It is the artist’s most ambitious painting. One of Amsterdam’s 20 civic guard companies commissioned the painting for its headquarters, the Kloveniersdoelen, and Rembrandt completed it in 1642. It is Rembrandt’s only civic guard piece, and it is famed for the lively and daring composition that portrays the troop in active poses rather than the traditional static ones.
AkzoNobel is main partner of Operation Night Watch.
