For its fourth issue, Trigger #4: Together collaborated with photographer Susan Meiselas. The issue explores various forms of collaboration in photography. Sixteen contributions engage with strategies of co-creation that stretch notions of authorship and ownership, breaking through existing heteronormative, state-owned, or hyper-individual categories. Essays by Elspeth Brown, Ileana Selejan and Hettie Judah. Forms and conflicts of human and more-than-human togetherness explored by Jonathas de Andrade, Grace Ndiritu, Leigh Ledare, Dries Segers, Meghann Riepenhoff and Vincen Beeckman. Contributions from Debmalya Roy Choudhuri, Susanne Kriemann, Tuan Andrew Nguyen, Kaali Collective, Rehab Eldalil, Hoda Afshar and Anthony Luvera, who repurposed existing work in answering a call for collaboration.
