When it came to cameras, Claudia Andujar always carried two small, unobtrusive Nikons, so as not to intimidate the Yanomami Indians, whose lives she chronicled for nearly half a century. “I tried not to be noticed when I took my pictures,” Andujar tells me on the telephone from her home, in São Paulo. “I was very motivated to understand the Yanomami, and, through them, to understand myself.”

The 88-year-old photographer’s pictures of the Yanomami, who inhabit the Amazon rain forests and mountains of northern Brazil and southern Venezuela, are the subject of an entrancing retrospective on at the Fondation Cartier, in Paris, until May 10, before traveling to Milan, Winterthur, and Madrid. The largest European exhibition yet of Andujar’s work, “Claudia Andujar: The Yanomami Struggle” displays more than 300 images, a re-creation of the photographer’s deeply unsettling audiovisual installation “Genocide of the Yanomami: Death in Brazil,” and drawings by the Yanomami themselves.
