Philip Cheung is based in Abu Dhabi and brings a new sensibility to documentary and photojournalistic photography.  Many of his images exhibit a visual language more akin to the photographers of the New Topographics group.  There are complex relationships  in his work that make it incredibly interesting.  This goes beyond the subject of war torn countries and military training.  There is often a certain amount of subtext that keeps you looking.  I think this idea of subtext is extremely important in talking about successful imagery.  It can be a slippery term but I think it most closely has to do with a secondary story within the photograph that can either be visual or relate to subject. . . something to think about anyway.
