The book consists of different essays written by specialists, offering relevant information about what photography meant to Rulfo, the echoes that inspired his work, as well as a chronology of the most important events in Juan Rulfo's life in relation to photography.

The central part of the book brings together a significant number of images referred to in the essays, including some that have already become iconic in the history of photography, as well as others that were scarcely known or remained unpublished.

For the first time, the book allows us to see, in parallel lines of text and images, Juan Rulfo's career as a photographer—a pursuit that Rulfo mastered completely, but which was often overlooked or considered secondary to his literary output by those who only casually approached this vast body of work.
