Some fifteen years ago a disc of scanned photographs arrived in my office from a Dutch photographer unknown to me, named Robert Knoth. The photographs were intensely gripping, a multiyear project to document and explore the grim impact on the health of people, particularly children, caused by the nuclear accidents and aboveground testing that occurred in recent decades in eastern Europe. In 2006 PixelPress published “Nuclear Nightmares: Twenty Years after Chernobyl” as a conventionally linear 19-screen photo essay by Knoth and with reporting by Antoinette de Jong, but with a major difference —the photographs would ﬁrst be seen and pondered alone as images, and only by rolling over them with a cursor could the reader then summon a hidden caption. According to Greenpeace, after an exhibition of this work in Kazan, Russia, received extensive media coverage, the provincial government of Tatarstan canceled plans to build a nuclear reactor. More recently, an agency of the federal government there launched a program to relocate families away from the banks of the Techa river, polluted by radiation. The publications of these images and text, in digital and analog forms (a book by Knoth and de Jong, (Certiﬁcate No. 000358, was published in Europe), focused and stimulated debates on nuclear power in many countries and contested the points of view of certain international organizations as to its safety. The first week of its publication on PixelPress in 2006 attracted 500,000 readers, an enormous number at that time.
