I've waxed lyrical many times about Alessandra Meniconzi's Hidden China book, and it was with great pleasure that I realized she recently updated (and enhanced) her website with absolutely magnificent photographs of minorities in China, structured along the same chapters in her book.
I've said it before, and I'll say it again. If there's one travel photography book you ought to have on China, this is the one. If this still doesn't convince you, I believe the imagery you'll find on her Hidden China website will. This is travel photography and ethno-photography at its best.
As background, Alessandra Meniconzi is a Swiss photographer fascinated by the lives and traditions of indigenous people in remote regions of the world. After many years of working in Asia, she traveled in Iceland and became interested in the Arctic. She is the sole photographer for the books Hidden China (2008), Mystic Iceland (2007), and The Silk Road (2004), and she is currently working on the new book about Tibet, Arctic and Himalaya.
