Watch on SFlix. For Prism, Belgian filmmaker An van. Dienderen invited Brussels-based Rosine Mbakam from Cameroon and Paris-based Eléonore Yameogo from Burkina Faso to work together on a film in which the differences in their skin color serves as a departure to explore their experiences with the biased limitations of the medium. Photographic media are technologically and ideologically biased, favoring Caucasian skin. Such white-centricity means that the photographic media assume, privilege and construct whiteness.
