It may be argued again:
In the photo book quartet, five podium participants* talk about four photo books, put them through their paces and sometimes even almost touch each other's throats.

The "Fotobuch-Quartett+" is a format of the International Photoscene Cologne, the first event took place as part of the Photoscene Festival 2014 at the Museum für Angewandte Kunst Cologne (MAKK), afterwards the "Fotobuch-Quartett+" was a guest in the art spaces of the Michael-Horbach-Stiftung, the Forum für Fotografie, the Zephyr in Mannheim, the Cologne Art Book Fair 2015 and during the Photoscene Festival 2016 at the Museum für Angewandte Kunst Cologne (MAKK).
