What's also called a "camera man."
I'm sure he would have been very wary if asked to recommend a cameraman.
I also really liked "The Housekeeper's Diary". From Ms. Berry's day to day interactions with the Waleses at Highgrove, it really did paint a picture of how mercurial Diana was in her moods. I think this was the first book that I read that gave me the insight that Diana was a very complex individual and that together, Diana and Charles suited each other like oil and vinegar. They were just two vastly different people.
