Gasworks presents Refracted Spaces, a research seminar convened by Filipa César and Louis Henderson. Developed as a way to expand on their research for Op Film: An Archaeology of Optics, the event situates the work presented in the exhibition in a wider context, incorporating the critical perspectives and practices of various other thinkers, researchers and artists.

Together with Zach Blas, Denise Ferreira da Silva, Ana Naomi de Sousa, Olivier Marboeuf, Margarida Mendes, Rachel O’Reilly, Roque Pina and Lorenzo Pezzani, the artists will discuss the themes of their exhibition in relation to topics ranging from indigenous sea-navigation methods and cartographic law to forensic research of the Mediterranean refugee crisis; from aesthetic strategies of nonlocality, opacity and obscurity that interrupt optical surveillance to systemic racism embedded within technological developments; and from the materiality and ontology of blackness and black light to afrofuturist narratives of submarine resistance.

The seminar includes a conversation between Filipa César, Louis Henderson and Roque Pina, the protagonist of their film Sunstone and the keeper of the lighthouse at Cabo da Roca, Portugal – the westernmost point of continental Europe.
