-    Boris Eldagsen (*1970, photo by Jan Sobottka) studied fine arts at the art academies of Mainz, Prague, and the University of Hyderabad (India) - as well as philosophy at the universities of Cologne and Mainz. As a photomedia artist, he has exhibited since 2000 in institutions and festivals including Fridericianum Kassel, Deichtorhallen Hamburg, CCP Melbourne, ACP Sydney, EMAF Osnabrück, Bundeskunsthalle Bonn, FORMAT Festival Derby, Singapore International Photography Festival, Chobi Mela Dhaka, Noorderlicht Groningen and Kochi-Muziris Biennale. Since 2004 he has been teaching as a lecturer and visiting professor at international art schools (Victorian College of the Arts Melbourne, Photography Studies College Melbourne, Pathshala South Asian Media Institute Dhaka, Academy of Fine Arts Mainz, Furtwangen University and Escola d'Art i Superior de Disseny) and gives workshops for the Goethe Institute, festivals and museums (Fotografie Forum Frankfurt, Westlicht Vienna, New Media Scotland, Australian Centre for Photography Sydney, among others). Boris has been an appointed member of the German Photographic Academy ( DFA ) since 2013 and a member of the DGPh since 2023. He is a digital advisor to Roger Ballen and was " Head of Digital " at the DFA from 2016 to 2023 , for which he designed and managed numerous online formats on artistic photography. He is also a founding member of the "Technological Progress" working group of the German Photo Council , in which Germany's photography associations discuss the impact of AI on photography. His background as a university lecturer, photo artist and digital media freelancer makes him one of the leading experts in AI images and moving images. In December 2022, Boris was the first person in Germany to offer online workshops on the topic. Since then, he has taught over 70 workshops (as of summer 2024) and has continuously developed his teaching. He is internationally valued as a teacher and has trained many of today's opinion leaders. In April 2023, he turned down the Sony World Photography Award (Open Category / Creative) because he had applied with an AI-generated image to test whether photography competitions and a debate on the relationship between AI-generated images and photography were possible. His stunt became worldwide news and his image PSEUDOMNESIA | The Electrician became one of the most famous of the year.
