Abstracts of presentations

Irina Crina Anca SANDU

The presentation will give an overview of the PERCEIVE project (PERCEIVE - Perceptive Enhanced Realities of Colored collEctions through aI and Virtual Experiences) focusing on the Scenario 2, dealing with paintings and works on paper subject to color change. The case studies from MUNCH (2 versions of the Scream, one on cardboard and a hand-colored print) and the Art Institute of Chicago (watercolor on paper by Cezanne) will be presented as examples for the simulation of color changes using different approaches and tools. Thus, the contribution of the project in this scenario towards advancing novel tools and technologies for conservation and documentation will be shown on specific case studies with particular color change phenomena. In particular, the prototype Scream Time Machine will be used as example of the interdisciplinary methodology used by the PERCEIVE researchers starting from acquisition of scientific data up to creating 3D replicas and a board game for multisensorial applications.

One of the most visible forms of degradation in artworks is discoloration. Discoloration refer to color change in artworks, triggered by exposure to environmental factors (light, temperature, humidity) that modify the chemistry of the constituent materials. On one hand, for the sake of preservation and defining the optimal exhibition policy of a work of art, it is crucial to study the aging behavior of its materials and predict their future change. On the other hand, for tracing back the visual narrative and the history of an artwork, it is important to attempt its restoration and visualize its original colors. In this talk, different approaches to digitally simulating discolorations in The Scream (ca. 1910) painting by Edvard Munch will be presented, by integrating data from multiple sources: elemental mapping, color and spectral imaging, artificially aging experiments and archival records on color films.

Speaker bios

Irina Crina Anca SANDU is a Conservation Scientist (holding a PhD in Chemistry, 2003) working at Munch museum since 2016. She led several projects focused on the scientific study of Edvard Munch Collection, with internal and external funding. Main research interests she developed in the past 8 years are: interdisciplinary and multiscale studies and characterization of original artist materials and art-objects collections; study of color change phenomena in modern paints; 3D modeling/rendering and monitoring of polychrome/painted artifacts using complementary analytical approaches; development of non-invasive methodologies for the evaluation of conservation-restoration treatments (cleaning); creation and development of digital databases and immersive experiences; development and implementation of innovative Outreach and training/educational strategies for the investigation and conservation of cultural heritage. She is Project lead for PERCEIVE on behalf of MUNCH museum and coordinates the workaround Scenario 2 dealing with paintings and works on paper subject to color change.

Irina CIORTAN is a Postdoctoral Researcher at the Colourlab, NTNU, where she previously completed a PhD degree in Computer Science (2023), with a thesis entitled «Spectral and Multi-light Imaging for Cultural Heritage: Material Analysis and Appearance Reconstruction». Irina holds a joint MSc diploma in Spectral Science and Multimedia Technologies awarded by the 4-university Erasmus Mundus Consortium “Colour in Informatics and Media Technology” (2013) and a BSc in Computer Science issued by the Faculty of Cybernetics, Statistics and Informatics in Bucharest, Romania (2011). Currently, within PERCEIVE, she is mainly capturing data and designing methods for the digital simulation of color changes in artworks (painting, textiles, historical photographs).
