The proliferation of smartphones, image-based instant messaging services (e.g., Snapchat) and photo- or video-sharing platforms (e.g., YouTube, TikTok, Imgur, Instagram) is expanding the intensity and scope of visual communication as a mode of everyday interpersonal communication. At the same time, images, videos, and other visual media are playing an increasingly important role in various areas of society. Amid the advancing digitalisation of everyday social life in general, and of visual communication in particular, these media are becoming increasingly numerous and diverse.

This planned special issue is dedicated to these emerging visual forms of expression, means of communication and methods. By addressing the phenomenon of Big Visual Data from a social science perspective, this special issue explores — put briefly — extensive, complex, and dynamic visual data volumes, as well as the associated changes in the social meanings, functions, and ways of using images and visual communication media. It pursues three main interests: (1) To theoretically discuss and conceptually define the phenomenon of Big Visual Data in its various manifestations, especially regarding its special communicative quality and social potential. (2) To discuss existing methodical and methodological approaches, to critically reflect on their epistemological premises and scientific-theoretical backgrounds, as well as to develop and lay the foundations for new methodological approaches appropriate to studying Big Visual Data. (3) To empirically analyze and determine the epistemic nature of Big Visual Data, in relation both to digitally mediated social realities and to the visual processes of constituting and constructing social knowledge.

This special issue aims to comprehensively address the social phenomenon of Big Visual Data and the resulting scientific data as an independent form of producing, disseminating, and implementing knowledge, as well as examine in-depth theoretical-conceptual, methodological-methodical, and empirical-analytical questions. Accordingly, besides sociological papers, contributions from other fields — including philosophy and cultural studies, art and media studies, visual culture studies and image science (Bildwissenschaft), digital humanities, human-computer interaction, interaction design, creative artificial intelligence and information design, as well as neighbouring or related disciplines — are explicitly welcome. We are interested especially in papers that address one (or several) of the above thematic interests, thereby contributing to the overarching aim of the special issue: to combine a genuine epistemological interest with a social science perspective.
