Speaking in voiceover, Richard Mosse describes some of the main thematic concerns that were important to him during the making of Incoming and the Heat Maps series. These closely related projects, made using the same thermographic video camera, represent aspects of mass migration and human displacement across Europe, the Middle East and North Africa. The initial part of this short video shows primary source video footage used to composite Heat Map images, as well as time lapse video of the digital compositing process, and details of the resulting art works. The final section shows selected scenes from Incoming, which is an immersive 52 minute three screen video installation.
