Posso’s visual work has centered on corporeality and portraiture, at first through painting and at present through a photography practice that has a documentary purpose, aiming to capture the identities and corporeality of the Afro populations in contemporary Colombia. Her images take the form of the portrait and poetically explore the body as geography and ritual. From the perspective of the social sciences, her work is an exercise in memory on the presences, realities, and problems of Afro-Colombian populations.
