American photographer John McDermott arrived in Siem Reap in 1995, chasing a solar eclipse&mdashand stayed on, producing astounding images of Angkor&rsquos Unesco-earmarked ruins. A collection of his award-winning work now occupies the John McDermott gallery at the Anantara Angkor Resort & Spa&mdashno need to detour to the National Museum in Phnom Penh or track down an exhibit in New York. Like the originals of Angkor Wat, this too is an open-air gallery.
