Planetary Autography and Indexical Visualization

The Photographic in the Materialities of the Earth

Abstract

This essay proposes to expand the notion of Earth autography to the category of medialogical structure, highlighting how material marks—fossils, tree rings, footprints, stratigraphy—function as proto-photographic archives, predating human action. The Earth thus presents itself as an autonomous agent of indexical inscription, anticipating the processes of photographic technical media in a planetary autography where the material trace establishes the legibility of the world.

It is argued that these traces constitute a matrix of meaning for terrestrial materialities: indices that maintain a causal relationship with what they represent, transcending photographic anachronism as a vestige.

From photography to LIDAR, the visuality of the planet is redefined, interconnecting what the Earth reveals by itself with what technical devices make visible, a medial operation evident in the concept of the operative image (Farocki): the images, point by point, maintain contiguity with the material trace. Understanding photography as structure and process, beyond technical anthropocentrism, and perceiving the Earth as a dynamic archive of information, becomes essential in the production of planetary legibility — and how all matter is already a fossil operability.
