Photographic representations of the indigenous populations of the Amazon rainforest have often been limited to journalistic or anthropological images. Yet one artist and activist took a more intimate approach, seeking to represent the spiritual and cultural reality of the Yanomami people. Claudia Andujar started documenting their community in the 1970s, but swiftly took on the Yanomami cause as a personal and political battle. We went to check out a selection of her photos in a new exhibition at Paris's Fondation Cartier.
