Here's some really terrific imagery of Tibet by photographer Jamie Williams, who's based in Sydney, Australia.
His biography is unfortunately sparse, and apart from dividing his time between photographing editorial and commercial imagery, and pursuing his own personal projects, we know that he won quite a impressive awards to include Honorable Mentions in Prix De La Photographie (Paris), and that he worked with many publications to include Australian Airlines Magazine, In Style, World Expeditions, etc.
There are quite a few of photographs in Jamie's Tibet gallery that I ought to mention; the juxtaposition of the prayer scrolls and the Mani stones images, the Tibetan woman with the prayer wheel in silhouette (above), the woman cradling a baby near a pile of Mani stones, and the woman walking underneath prayer flags in a village...just to mention a few. The gallery consists of 47 images, so you'll need a few minutes to enjoy them. And the photographs are big...really big! The size that photo editors want and like.
His travel galleries also include imagery from Nepal, India, Kashgar, Kyrgyzstan, his native Australia and Papua New Guinea.
