The 2018 edition of the Photobook Festival explores the theme Borders and Boundaries.The theme Borders and Boundaries is intended as a critical response to the increasing use ofborder controls and the increased social and economic inequalities which exemplify boundary making.A series of six talks on Sept 28 and 29 explored the uses of the photobook as an exhibition form across the issues and challenges of decolonisation, urbanisation and gentrification, migration and legacies of conflict. Invited speakers were Julia Tedroff, Jeuno Je Kim, Daniel Jewesbury, Johan Öberg, Mary Coble, and Sanjin Pejkovic and guest photographers were Katarina Despotovic, Magnus Sundberg, Karlsson Rixon, Michelle Eistrup, Igor Čoko and Nina Mangalanayagam. The talk series was hosted at the Hasselblad Center which also included several exhibitions of photobooks selected via open call, a curated exhibition of photobooks on the theme and in partnership with this years partners:Matthew Carson, Emelie Dunne and Fred Ritchin from ICP (New York), Autograph Association of Black Photographers (London), Membrana (Slovenia), Polish Paradise (Poland), Belfast Exposed (Northern Ireland), The Swedish Photobook Award (SFF), Swedish Book Art (National Library) and the Nordic Dummy Award (Oslo).The 4thedition of the photobook explored the theme Borders and Boundaries and used the seminare and workshop as a format to bring together practitioners and audience in a conversation on important issues brought up in the participants projects. Each participating photographer had a conversationpartner for their talk. The talks included were:1."Bridging Art and Text"Michelle Eistrup in conversation with Jeuno Je Kim.2."Not being Sri Lankan"Nina Mangalanayagam in conversation with Daniel Jewesbury on her work in progress.3."Engaged Documentary Photography"Igor Čoko in conversation with Sanjin Pejkovic.4.“Den urbana fronten –fotografi som forskning” Katarina Despotovic in conversation with Julia Tedroff.5."Memorable Mobility" Karlsson Rixon in conversation with Mary Coble.There were also several publishers and organisations invited to exhibit on the theme with, among others, th International Center of Photography Library in New York who curated an exhibition of books from their collection on the theme with material that is less obvious and perhaps lesser known, interpreting the theme in various ways, historical, political, social, and psycological boundaries. The exhibition was curated by Matthew Carson, Emily Dunne and Fred Ritchin.There was also a curated open call exhibition including submissions from academics, photographers, activists, and artists, whose use of photography responds to the festival theme.The photobooks received ranged from photo documentation on the increasing use of border controls and the increased social and economic inequalities which exemplify boundary making and photobooks that counter the discourse of far right populism and the increased use of borders and boundaries to separate and divide.Continuing on the working method started at the 2017 Fotobok GBG with thematic exhibtions I tried to expand and make the theme seap through each aspect of the programme. The conversations and workshops worked well with the theme and the diversity of issues in the bodies of works presented and the exhibtions functioned as a backdrop giving a the activities as context to exist within. The open call exhibition and book sfrom Autograph ABP and Belfast Exposed will be exhibited in Copenhagen and Oslo next and will form the foundation for the ongoing work for 2019.
