The video work 'Parkranger' (2019-2021, 19:00) is the result of a collaboration between multimedia artist Nike Arnold and anthropologist Isabel Bredenbröker. It shows Görlitzer Park in Berlin as a deceptively calm surface. A seemingly insignificant video track glides through the park, leading the viewer's gaze from the perspective of passer-by towards intimate scenes with park visitors. What the visual content intentionally withholds, the audio track makes up for: dialogues with the police, people experiencing astonishing and disturbing things in the park, casual conversations and repeated comments on the presence of cameras and microphones in the park, i.e. the presence of the filmmakers. That way, the work addresses the research process in a place that is extremely sensitive to the presence of surveillance. At the same time, it provides a balanced insight from a variety of perspectives into a place where multi-layered processes of negotiation arise around legality, use, the right to exist and public space as a shared free space. The film quotes from Berlin's park rules and emergency laws for crime-ridden places while amplifying the voices of drunks, activists, dealers and sparrows.
