Visualization and Communication of Digitized Collections of Art Visualization and Communication of Digitized Collections of Art Sonja Gasser The PhD thesis „Visualization and Communication of Digitized Collections of Art – Visual Culture at the Intersection of Art History and Media Technology“ sheds light on the challenges and opportunities arising from the digital transformation that art museums and art historians face today. Digital collections of art museums are the starting point for an in-depth examination of the implications the availability of digital images and metadata has for museums and art historians. Having data available is a completely new situation to think about presenting art, public engagement, and research. Only if museums and art historians are aware of the peculiarities that digital technology offers, they will be able to use digital collections as a valuable resources for the cultural institutions’ purposes, the interests of visitors and users, and for art historical research. This requires understanding what data is and how computing technologies can be applied to digital images and metadata for the retrieval, manipulation, analysis, visualization, presentation, and interpretation of data. The PhD thesis aims to raise the awareness for a broad range of topics that are inextricably linked to a thorough understanding and use of data from digital art collections with a sensibility for the possibilities of digital technology. It therefore contributes substantially to the notion of the digitally competent museum, to the fundamentals of Digital Art History, and to the Digital Humanities with an emphasis on the visual.
