Belgian filmmaker An van. Dienderen invited Brussels-based Rosine Mbakam from Cameroon, and Paris-based Eléonore Yameogo from Burkina Faso to make a film in which their different skin colour serves to explore the limitations of the medium. Photographic media is technologically and ideologically biased, favouring white skin. Such white-centricity means that the photographic media assume, privilege and construct whiteness. Prism problematises the neutrality of the camera.
