The classic Posing Guide. Rules for posing people for portraits. Drawn in cartoons, making it easy to follow. "Serious, invaluable advise on how to pose people in photographs" Amateur Photographer
While I will probably need something more eventually, this was an excellent starter guide for posing people.
While short, the author covered a wide range of situations (not just 'cute girls in skimpy clothes'). Examples were given in simplified cartoon format with a significant amount of humor splashed in.
My main criticism is this is, as the name implies, a 'pocket guide'. I do not consider this a drawback since this is exactly what it claims to be, but I do wish it was longer and went over more of the 'why' of things. While not quite a cookbook it was more in that direction then a 'fundamentals' book. It would be interesting to see the same author apply the style of this book to something more in-depth.
