3D digitization of cultural heritage has long been used to preserve information about cultural heritage (CH) objects such as architecture, art, and artifacts. 3D dissemination of CH objects through technologies such as augmented reality, virtual reality, and 3D printing have impacted the fields of art history and cultural heritage and have become more common. Yet, studies that go beyond the technical aspects of 3D technology and treat such topics as their significance for restoration, conservation, engagement, education, research, and ethics hardly exist. The aim of this paper is twofold: on the one hand, it aims to get a better understanding of the applicability of each technology for different purposes (education, research, conservation/restoration, and museum presentation), and, on the other hand, it focuses on the perception of these technologies. This research was carried out by combining a literature review with quantitative and qualitative analyses of the data acquired through (1) a questionnaire of eleven questions and (2) a workshop with a group of specialists and non-specialists who were asked to brainstorm about the different uses of the 3D technologies and their applicability to their areas of work and research. Based on the analysis of these quantitative and qualitative data, we provide some criteria for using 3D digitized and printed reproductions to enhance cultural experiences. The results demonstrate the importance of carefully designing 3D interactions in the personal and cultural contexts of end-users and cultural institutions in order to create authentic cultural experiences.

Various types of digital and physical three-dimensional facsimile technologies (e.g., high-definition digital modelling and 3D printing) have entered the art world and have become increasingly important for research and presentation purposes. Yet, studies that go beyond the technical aspects of (3D) facsimile techniques, such as their significance for the conservation/restoration field and museum display, are scarce, especially in the case of easel paintings. Furthermore, studies that analyse the perception of these methods and, consequently, their impact on the authenticity of the original painting, do not exist to our knowledge. The aim of this research is twofold: firstly, it evaluates a viewer’s perception of various facsimiles; secondly, on the basis of this analysis, it aims to gain a better understanding and provide an overview of the applicability of (3D) facsimiles of artworks for presentation purposes and potential users (technical art historians, conservators, curators, material scientists and museum visitors). This research was executed by combining a literature review with quantitative and qualitative analyses of the data acquired through a) a questionnaire of 17 closed and open-ended questions and (b) an on-site session at the Mauritshuis museum (The Hague, The Netherlands). Based on analysis of the data collected through these activities, this paper attempts to provide an indication of the current attitude towards (3D) facsimile methods as well as to present some criteria of using these methods in a museum environment.

Various imaging techniques are used to visualise issues regarding a painting’s appearance before, during and after conservation treatments, i.e. visible light photography (VIS) raking light photography (RAK), ultraviolet fluorescence photography (UVF) and reflectance transformation imaging (RTI). However, these techniques cannot always visualise and/or quantify conservation issues. This paper presents a new approach: colour, gloss, topography imaging (CGT). CGT’s applicability as a non-invasive tool for evaluating and documenting conservation treatments in comparison to VIS, UVF, RAK and RTI is discussed. Applying this to case studies with different conservation dilemmas illustrates the technique’s potential and drawbacks. CGT can visualise issues such as gloss variations, resulting from (previous) cleaning tests, (partial) varnish removal, and possibly dirt and material degradation. Furthermore, CGT can elucidate topographical issues such as bulging, and losses, and also visualise high-frequency surface variations (e.g. canvas weave and crack pattern). This results in an improvement of documenting a painting’s condition, and the evaluation of treatments and their effects on the visual appearance may be quantified. In conclusion, this research shows that CGT is able to better visualise texture, gloss and colour information than existing techniques like technical photography, facilitating a more precise documentation and localisation of previous and current conservation treatments.

The consequences of the coronavirus and the physical limitations it imposes on museums and their visitors force museums to rethink cultural identity and to approach the exhibition of material artworks differently. Only a limited number of people are allowed to visit the museum at one time, booking time slots is mandatory, making it difficult to welcome visitors. As most Dutch museums are largely self-funded, the lack of tourists, visitors, educational programmes that generate income, together with the insufficient financial support of the Dutch government, have greatly impacted their policies. This report analyses the coronavirus' effects on the role of museums within the Dutch 'anderhalvemetersamenleving' (one and a half meter society). This report offers an overview of the changes that have taken place in Dutch society due to the limitations of physical interaction with artworks and the museum space as well as the way Dutch museums have reacted to these consequences. Lastly, this report offers an analysis of the success of these new developments and the challenges that still need to be overcome. Thus, ways will be proposed in which Dutch museums can learn from these actions in maintaining their critical function in society.
