I've come across Jean-Claude Louis' work through the many photographic contests he won in 2007 and 2008. For instance, he participated and won (in specific categories) awards in National Geographic International competition, the Travel Photographer of the Year competition (two categories), and the B&W Magazine Portfolio Competition. I also recently saw his work published in Outdoor Photography. For those interested in winning photography contests, his images will certainly offer you clues as to what makes them click with judges.
His biography tells us that he's a physician and a scientist, working in biomedical research until 2007 when he pursued photography full time, specializing in documentary photography. Self taught, he is influenced by Steve McCurry, and this can be seen from his Tibet gallery in particular.
