This is part and parcel of how the subject interacts with the background too.
No sorry Mark, I can't agree it depends on the focal length of the lens, wheras this certainly applies to standard and wide angle lenses with medium telephoto lenses ie. 85, 90,100,135mm you can get tight head shots without distorting the facial features which is why they are considered "portrait lenses", once you get lenses longer than 135mm they have the opposite effect to large noses, and tend to flatten the features.
