This practice-based artistic research departs from the Green Rays a form of knowledge where perception, technology, and cultural expectations intersect. A rare and fleeting optical event which occurs at sunset, this phenomenon is mostly, if not exclusively, mentioned in European cultural and scientific contexts; an understanding of the Green Ray therefore requires a constant reformulation of strategies. This can be particularly valuable for science, in its efforts to study indiscernible elements, and for the arts, by looking at forms of activation reliant on embodied knowledge and mutable processes. Rather than treating it as an optical curiosity or romantic metaphor, this research approaches the Green Ray as an epistemic and affective experience: a transient event that elicits the limitations of seeing and the conditions of knowledge production. This artistic research proposes a method which relies on the co-emergence of observer, environment, and technology.
