The Moving Camera-Witness explores how the act of filming can become a somatic and relational practice. Drawing from Authentic Movement and informed by an interview with practitioner Eila Goldhahn, an artist, author and academic (who has researched The Discipline of Authentic Movement and originally coined the term ‘camera-witnessing’), the video essay unfolds across six chapters. It begins by exploring the concept of witnessing, invoking different perspectives of the term. The second chapter traces the origins of Authentic Movement, establishing a foundation for understanding how it is practiced. This is followed by a recorded conversation with Eila Goldhahn, in which she shares the ethical and aesthetic dimensions of her ‘camera-witnessing’. In the fourth chapter, Rivoal offers personal insights into her practice as a moving camera witness. Departing from a static witnessing position, she investigates how the camera might become an extension of the mover’s body—responsive, attuned, and alive to the relational field. The essay then moves outdoors to Hackney Marshes, where Rivoal’s long-term collaboration with Claire Loussouarn has extended the practice into a site-responsive method of filming.
