Was Robert Kincaid really a photographer for National Geographic?

NATIONALGEOGRAPHIC.COM has provided the answer: "Alas, the sexy, middle-aged photographer, portrayed by Clint Eastwood in the film that followed the book, is pure fiction. There is not, and never was, a Robert Kincaid here, although some of our photographers have shamelessly encouraged the comparison."(http://www.nationalgeographic.com/ngm/faq.html#ocho)
