Issue 16, "the invisible", explores how invisibility organises the field of the visible: in any process of image-making, the invisible marks an aesthetic, technical or social discrimination, a sign of what is set aside because it is refused appearance or because it resists representation altogether. The issue includes a portfolio by Estefanía Peñafiel Loaiza, a dossier with Damarice Amao, Camille Aymé and Sergio Valenzuela Escobedo, a laboratory section by Timothée Pugeault, an interview with Wolfgang Tillmans, and a portfolio by Geert Goiris.
