Shot in Quebec, Canada, The Subterranean Blackness of Roots is a 16mm film triptych which uses several processes specific to analog cinema (hand processing, optical printing, photochemical alteration). The film seeks to show the sensory experience of the invisible life of stones, plants and the nature that surrounds us. It’s a dive into the heart of matter, the essence of the vegetal world and the nourishing earth.
