Contribution at the symposium 2018
 “forensic science photography”

In co-operation with Phase One Cultural Heritage I talked about the development of opto-electronic multispectral imaging processes in the last two years and showed apllication examples from workshops at BKAs and LKAs.

Multiband at the Stephansdom in Vienna

In October, I examined a wall painting in St. Stephen's Cathedral in Vienna. The image information have been evaluated in collaboration with Roland Lenz, Professor of Conservation and Restoration of Wall paintings, Architectural Surfaces and Stone Polychromy at the State Academy of Fine Arts, Stuttgart.

Multispectral Imaging at SMK In Copenhagen

In August, in cooperation with SMK (Statens Museum for Art), CATS (Center for Art Technological Studies and Conservation) and Phase One, I did multispectral imaging of a Bruegel the elder Painting.

Spectral imaging in Müstair

In the summer of 2018, the conservation of the wallpaintings in the middle apse in the monastery of St. John in Müstair began. In the upper area and in the dome, in consultation with the scientific director Patrick Cassitti, I examined preservation conditions and distribution of the paint layers.

Infrared Fluorescence in St. Prokulus

In December 2017 and February & May 2018 I traveled to Naturno to study the murals in St. Prokulus. My interim report will be published in the publications of the South Tyrolean Cultural Institute, Volume 10, St. Prokulus in Naturns / San Procolo a Naturno.

Investigation in Freiburg Minster

In February and April I accompanied the studies and the conservation of the wallpainting of the Peter and Paul chapel in the cathedral of Freiburg im Breisgau. A partial area was recorded photographically in the stitching process, in high-resolution, from UV to infrared.

MSI in St. Sebaldus Church in Nuremberg

Three late-medieval, side-by-side murals that are in very poor condition due to war damage were the focus of my photography campaign. The improvement of the readability of the depicted scenes played a role as well as the investigation of references to the restoration history.

 

Piero della Francesca Conservation

At the end of March, the masterpiece Piero della Francesca The Resurrection was presented. At the end of the restoration, at the end of February, I documented the artwork for the last time in visible light and with specially selected wavelengths in the stitching process.

MSI in Weimar

On behalf of the Klassik Stiftung Weimar I examined fire-damaged documents with charred edges using spectral and multispectral photography. The focus was on the readability of the font.

Profane room settings from 13th century

A test project investigating decorative paintings using spectral photography took me to Erfurt. There I photographed remnants of a former color version in the " Raum mit der Blütendecke" commissioned by the University of Applied Sciences Erfurt.

Multispectral Photography

My 3-5-day workshops focus on the application of multispectral photography in the forensic investigation. A theoretical introduction is followed by practical applications and the evaluation of the image information.

Multispectral Imaging

From April to July 2017, I examined parts of the Heiligkreuzkapelle in monastery St. Johann in Müstair.

Multispectral imaging from Ultraviolett to Infrared – non-invasive examinations and the  possibilities and limits to analyze conservation state and pigments. Examples: paintings, frescos, textiles.

Meeting information & program

Multispectral Imaging

In September 2016 I accompany again the restoration of the fresco in Sansepolcro. To document the cleaning of the fresco, I use the UV fluorescence photography. Thus cleaned and uncleaned image areas are clearly visible.

Technical contribution

Ultraviolet-Induced Luminescence Imaging: Giovanni Verri, Annette T. Keller, Francesca Piquè, Alfredo Aldrovandi.

Report of the project ORGANIC MATERIALS IN WALL PAINTINGS. The Getty Conservation Institute summarizes all scientific findings and makes them available for download.

Cappella Peruzzi

From 11 December impressive UV fluorescence images of the entire Cappella Peruzzi ( Florence ) will be on display at the Palazzo Reale in Milan. The images I made during my two-month photo campaign in autumn 2012 will be showcased as multimedia installation at the Giotto, l'Italia exhibition.

Multispectral Imaging

I was highly pleased with the media coverage that commenced even before the restoration process had begun.

I segreti del dipinto piu bello del mondo
Comincia dopo Pasqua il restauro della Resurrezione di Piero della Francesca a Sansepolcro.
Ma intanto la prima scoperta: l’artista ha impiegato 15 giornate d’affresco per realizzare il dipinto

The mystique of the world’s most beautiful painting
After Easter the restoration of the “Resurrection of Jesus Christ” by Piero della Francesca will begin in Sanselpolcro. Here in advance, the first finding: The artist implemented the Fresco in 15 “Giornate”.

Documentation & art diagnosis

The works of Pollaiolo take centre-stage in a running project with the Opificio delle Pietre Dure in Florence: 27 panels are being documented and diagnosed as part of the restoration process. The project will conclude in spring 2015.

Training

In 2013, I prepared and held a 3-day training on the topic of multispectral imaging for the employees of the Associazione laboratorio di diagnostica in Spoleto at the University of Perugia. The participants received an in-depth insight into the theory and practice, techniques and projects.
