La invariante temporal by Marcelo Grosman brings together a selection of works created from the late eighties to the present day. The book reflects on the use of photography in the contemporary space of the image. The moving image and the moving subject are the synthesis of a conceptual exercise inscribed throughout the work. The arrangement of the images, far from being chronological, reflects various intellectual explorations, revolving around the domestication of the body, social taxonomies, secret languages, the iconography of gesture, and the uses of technique among multiple quests.
