Filipa Cesar @ Gasworks

Op-Film: An Archaeology of Optics, is a collaborative exhibition by artists and filmmakers Filipa César and Louis Henderson.
The exhibition comprises a newly commissioned film and installation exploring how optical technologies of military and colonial design – from lighthouse Fresnel lenses to global satellite navigation systems – both inform and are informed by Western models of knowledge. Taking a critical approach to the ideologies behind the development of these instruments of guidance and surveillance, the artists consider how imperial gestures of discovery, revelation and possession are embedded in associations between seeing and understanding, light projection and enlightenment.
