Pieter Bruegel the Elder under the PLDs

In 2019, worldwide attention will be paid to Pieter Bruegel the Elder. It is then exactly 450 years ago that the famous artist
passed away. Therefore, Bruegel will be celebrated in exhibitions all over the world. But, new exhibitions require new research and research techniques. That’s why the Royal Library of Belgium and the KU Leuven joined efforts in the context of a BRAIN-BE project funded by Belspo. FINGERPRINT is an interdisciplinary project in which art historical and artistic research, digital imaging and image processing, conservation and restoration projects and data management are brought together. All these efforts include as well the use of both the White Light Portable Light Dome (WL PLD) and the Multispectral Portable Light Dome (MS PLD). Their datasets are being combined with the output of standard technical photography techniques. The ultimate goal of the FINGERPRINT project is to join all this static and interactive information and develop tools and methods to analyse objectively drawings, prints and engravings of this master and others; to create a platform to examine and understand a historical artifact automatically.

A first introduction article on this new project in which the PLD systems are being applied has been published in the journal Science Connection by the Belgian Science Policy Agency Belpso:

Microdome imaging workshop at the J.P. Getty Museum

RICH000535Between January 27th and February 3th the RICH team has been working together with the scientists and conservators of the J.P. Getty Museum and Research Institute in Los Angeles. Various artifacts of the Museum collection have been monitored and studied with Photometric Stereo such as medieval manuscripts, master drawings, bookbindings and daguerreotypes.

Both White Light and Multi-Spectral Microdomes have been used. The RICH Project, the technical background and the research targets have been highlighted the on February 2nd during the lecture: Microdomes and Manuscripts: Multi-Spectral and Photometric Stereo Imaging for Illuminations, Drawings and Documentary Heritage. After the lecture, a hands-on workshop was given at the Imaging Studio of the Getty Center.

RMAH – MS Imaging of Mummy Portrait

In collaboration with the RICH project and the ESAT labs (both KU Leuven) the Royal Museums of Art and History coordinates a pioneer project in which the multi-light Portable Light Dome is transformed into a Multi Spectral dome equipped with IR, Red, Green, Blue and UV LED light sources. This short video demonstrates the acquisition process with the fist developed MS microdome prototype of a Fayum mummy portrait (Egypt, Roman era) at the Brussels museum.
