In a series of eight critical essays on photography, written in the course of a long professional experience, Joan Fontcuberta reflects on the creation of images and on the culture that would like them to be an expression of truth and proof of existence.
Rebelling against the belief that the photographic message does not need to be interpreted as, by nature, "evident", Fontcuberta questions the idea of ​​photography as a mirror of reality and an expression of truth and the role of the photographer, who, cruelly , of the soul of what it portrays only returns the external form.
Continuing with examples taken from various fields of culture - including literature, cinema, theater -, the Author parallels photography and writing and illustrates the ways in which the image represents or, rather, simply attracts.
Il Bacio di Giuda (The kiss of Judas) is a classic of the theory of photography, already present in the bibliography in university courses of visual communication.
