I absolutely love the work of Dave Nitsche, so clean, simple and sharp yet requires so much skill to produce images that are this stunning.

Also like CT, I admire any photographer that goes into war zones, areas of famine or extreme suffering and then with total disregard to their own health( be it physical or psychological), shoot pictures to show the outside world the story behind closed doors.
They are a world apart from us wanna be's.
