This is a `coffee-table book' of photographs of the 30 or so different ethnic groups in Burma, framed by sparse but intelligently written text and running to 236 pages. It was published in 2001, so the photography mostly dates from the 1990s.
A critical reviewer on the amazon.com site has commented that some of the pictures were staged - i.e. people dressed up for the occasion. If true, this does not make the images any less authentic. I personally travelled widely through the Golden Triangle region in the 1990s and can confirm that most of these people notably the various tribal Hmong, Akha, Lahu and Keren did in fact wear elaborate tribal dress precisely like those pictured in Diran's book, every day. Akha, Hmong and Lahu women woould come down from the hills to the markets in places like Pak Beng, Mai Sai (where the border crossing between Myanmar and Thailand was open) and the hill villages around Kengtung. Devotion to wearing tribal dress was especially true of the women whilst the men would more often work in jeans and T-shirts bought in these markets. Some of the people I met especially in NW Laos and NE Myanmar had never met westerners, and I think Diran's book is very authentic and brings these people to the attention of a wider audience with honesty and sensitivity. He does not dwell on the Myanmar military government's genocidal war against some of these people, notably the Keren, but does not completely neglect to mention it either.
The book concludes between pp196-233 with a 37-page `Ethnographical History', written by Gillian Gibbs and Martin Smith. This text contains around 70 monochrome photographs from the James Henry Green collection or the British Library, of the peoples of this region photographed in the 1920s.
Diran's book is a very good example of its type: accurate, sensitively written, good photo selection and first class production values. He obviously put in a lot of work here, to good result. The only downside is that it seems to be very expensive on Amazon: I got mine in a London bookstore a few years ago for GBP9.95 (it still bears the price sticker), but prices on Amazon currently run much higher than that.
