I have always liked the idea of being as invisible as Cartier-Bresson, of being able to photograph as he did without intruding or changing anything. In northern Pakistan, I was certainly visible but not really noticed. Muslim women stay at home, protected by their men, and if I were native-born, a begum sahib, I would have been at home too. But because I was a foreign woman, a mem-sahib, and permitted by the men in my family to roam the world, I was considered unimportant or unchaste — or both.
