Multispectral data for a sketch of Peter Paul Rubens (1546 – 1640) depicting Diogenes' Search for True Man
No full textRecently discovered in Paris, this sketch is one of two known copies of a lost original sketch for Rubens 1615 painting of Diogenes' Search for True Man, currently located in a European private collection. The other known copy of the sketch was made in 1635 and is housed in the Städel Museum in Frankfurt.
The Parisian sketch is made using the "trois crayons" technique on paper, presumably by a talented student in Rubens' workshop before it was corrected and revised by Rubens himself using black chalk. The aim of analysis using Multispectral Imaging (MSI) is to improve the legibility of several inscriptions in red chalk or red ochre on the back of the sketch, which are obscured by remnants of adhesive from a previous mounting. This technique was paired with analysis by Infrared Reflectography (IRR).
Data is also included for an inscription at the back of a book, under the data label APOPHTHEGMATA.

Album of Elisabeth Dreyschock (née Nose), Stadtgeschichtliches Museum Leipzig, A/2013/382 (1851–1895)
No full textThe album is kept in the Stadtgeschichtliches Museum Leipzig (accession number A/2013/382). It has been digitised at the CSMC as part of the project ‘Creating Music Albums as Originals Made of Originals’. The manuscript measures 21 × 31 cm (landscape) and contains 90 folios plus one bifolio as loose addition. It belonged to the singer Elisabeth Dreyschock née Nose (* 1832 in Cologne, † 1911 ibid.), wife of the Violinist Felix Raimund Dreyschock.

Multispectral Imaging Data and Beamtime Data of Samples Analysed During the P06 Beamtime at PETRA, DESY
No full textParchment and papyrus samples were multispectrally imaged after a beamtime at beamline P06 at PETRA III at DESY.
One of the parchment samples showed a visible relaxation after irradiation with X-Rays.
This relaxation is documented over time using the Megavision E7 MSI system and compared with others.
Samples were irradiated with 18keV and at 7.2keV at the beamline P06 at PETRA III at DESY.
Imaging was performed on 4th of October 2016.
Beamtime data is included in this uploa

Multispectral Imaging Data of Codex B captured at Biblioteca Apostolica Vaticana
No full textThis multispectral data of the two bifolia of the Codex B was captured at the Biblioteca Apostolica Vaticana in June 2023. The goal of the imaging session was to test with the MSI wheteher and how to visualize reinked letters, corrections and other otherwise invisible features of the manuscript with the goal of subsequent complete MSI capture of the whole codex. The MSI images are intended to help choose smaller areas and spots for measurements with XRF, Raman or FTIR. Additionally, they provide information about the conservation condition, for example displaying levels of bio damage. In this MSI campaign only two bifolia were imaged. The MSI campaign was co-organised by the Biblioteca Apostolica Vaticana, the Centre for the Study of Manuscript Cultures (CSMC), the Bundesanstalt für Materialforschung und -prüfung (BAM). Imaging was carried out using the CSMC MegaVision multispectral imaging system. The MSI system was operated by the CSMC staff, the object was handled by the staff of the Vatican Library digitization and conservation departments. (See contributors)
Preview JPEGs in sRGB color space are compressed and of lower quality and are only intended for quick previewing. Original, high quality, CIELAB TIF images can be found in the folders within each ZIP file. Each uploaded ZIP file contains the flattened, processed and color images for both bi-folia of the codex. Raw images are not included in this dataset simply for size reduction purposes. Raw images are stored internally on the servers of CSMC and, if necessary, can be separately accessed upon a reasonable request. For information about filenames and folder structure as well as MSI system, please see the files in the "info" folder and read the Brief Descriptions of Multispectral Imaging (MSI) Datasets.
Image processing was performed with Hoku image processing software. In each processed folder there are 6 images. A visible light color image called "RGB", an image highlighting the reinking called "Reinking", an image highlighting the texture called "Texture", an image showing the bio damage on sheets where probably mold is present called "Bio Damage", as well as two pseudocolor images called "400_Composite" and "450_Composite" showing fluorescing materials present on the sheets and a "Pseudocolor" image which color-codes the reinking in blue and red for better visibility and as an alternative to the other "Reinking" image
Multispectral Imaging Data from Samples for Research Project: "Quantitative Monitoring of Works of Art on Paper With Imaging Spectroscopy"
No full textThe goal of this research is the investigation of potentials and limits of UV-VIS-NIR Hyperspectral Imaging (HSI) and Multispectral Imaging (MSI) for the non-destructive quantitative monitoring of spectral changes that occurs in historical papers and writing media during exhibitions at the Rijksmuseum.
Four spectral imaging instruments in Europe have been tested using the same set of samples collected from original discarded papers of the Rijksmuseum and reference targets.
The samples include: an historical blue paper, a light sensitive pastel, papers with foxing and metal intrusions, a sanguine (red chalk) and the Blue Wool Standard grade 1.
Data presented here is part of the research and is the Multispectral imaging data captured using the Multispectral imaging system of the Centre for the Study of Manuscript Cultures in Hamburg.
