Here's the work of a consumate travel (and documentary) photography professional which I take delight in featuring on this blog. Alison Wright has traveled the corners of the globe during the past 20 years, documenting endangered cultures and highlight human rights issues which she cares about.
She's represented by the National Geographic and Corbis, and has been published in so many publications that it's virtually too long to list them all here, but among those are the National Geographic, Adventure and Traveler magazines, TIME magazine, The New York Times and so on. Her talent was recognized with various prestigious awards, and she published her work in her many book.
I won't single out any particular gallery on her website, as her images are all spectacular, but I will say that the one above of the woman in burqua, and the man in the alcove at Mazar-e-Cherif is, in my view, perfection.
