Camera Geologica : An Elemental History of Photography by Siobhan Angus.

The article reviews *Camera Geologica: An Elemental History of Photography* by Siobhan Angus, which examines photography's material and social connections to mining and global capitalism. Angus traces the use of metals, minerals, and fossil fuels—such as bitumen, silver, platinum, iron, uranium, and rare earth elements—in photographic processes from analog to digital, highlighting their environmental and social impacts. The book employs a historical materialist framework to reveal photography's role in colonial violence, extraction, and industrialization, emphasizing the medium's tangible ties to natural resource exploitation. Angus argues that understanding photography's extractive foundations is essential for addressing its ongoing implications in environmental degradation and global inequalities.
