When he originally went to Ethiopia it was just him and his mate along with a guide. He only returned with the crew to document the giving back of the photos. They still had to travel via plane, train, log boat, and automobile to get to some of tribes he visited. They wiped their butt with water and their hand for goodness sake. These guys lived it, it's not as though they just rolled in, snapped a few shots and left. The fact that he hauled his lighting gear along with him to get the shots that he did makes it just that more remarkable if you ask me. Not too many people would go to such lengths to document and create something as remarkable as what he was able to get. The reactions of the tribes people alone, when he gave them their photos I think emphasizes the significance of his achievement.
