David Burnett comes across as very much like a 'regular guy', who has developed a great talent for photographing the 'moment'. While viewing a filmed interview with Burnett I've come to the same conclusion, a very easy person to like.
My only minor quibble with the story is that one could get the idea that Burnett took the famous "napalm girl" photograph. That photo was taken by Nick Ut. I don't think that is what the writer intended, just that Burnett had walked the same road where that photograph was taken.
