That is actually a pet peeve of mine.... Having all sorts of weird stuff coming out of the top of peoples heads... sometimes it is funny... but most of the time it is just bad photography.
I have a friend who is a "Professional" photographer who has absolutely NO clue how to frame a pic so that this doesnt happen.
His pics always look like crap. Feel bad for the guy, but you either have it or your don't...he needs to find a new profession!
