The past days (May 11-13) the RICH team organized a workshop on multispectral imaging at the Imaging Lab of the University Library KU Leuven, which coincides with the implementation of the Multispectral Microdome. Mike Toth, Bill Christens-Barry and Alberto Campagnolo set up their imaging system for multispectral capture developed during the Archimedes Palimpsest project. Eric Joakim of Phase One kindly provided an IQ260 Achromatic digital back and IXR camera for capture.
Western and eastern paper, parchment and papyrus documents and archaeological objects such as Egyptian execration statuettes were monitored. These objects were captured through 16 different spectral bands, ranging from UV to IR. We were specifically looking at censored, deleted and faded texts, pictorial layers and false color visualisation of polychrome layers of medieval illuminations.
The Timbuktu manuscripts, which are being researched and digitized at the moment at the Imaging Lab, were also the focus of attention.
