The book features the series: Hemogramos, Constelaciones and Semiopolis. This book brings together 3 projects by Joan Fontcuberta, projects that partake of a critical practice of photography within the context of contemporary art. In ‘Constellations’, ‘Haemograms’ and ‘Semiopolis’, paradox, ambiguity, trompe-l’oeil and the investigation of the photographic trace form the common nexus. These images beat a path towards hidden, but ever-present, worlds. Behind dramatic celestial landscapes, urban utopias glimpsed in science fiction, or abstract and minimalist smears of blood, another reality emerges, ironically enough.
