Shadow Casting is tool to engage with representation as performative process of study as an absence. It engages with the tools of enlightenment and explores light as a direct engagement of body , space and memory. It transforms the monolithic practice of singular frontal practice of study into reciprocal process of mutual engagement between the explorer and the reference transforming both into a participatory element of study and reflection. It critically engage with the idea of representation into a mutually shared space of presence and absence.It transforms light from being a source of illuminating into a physical material itself and becomes a direct material and the interface between multiple subjects de-centering the notion of centre and the periphery, major and the minor and transforms study into an encounter of multiple centres. It explores light as a transforming phenomenon of physical light to artificial light and explores its presence a mediator between different interpretation of time and space.
