Ah yes... The reflection in the 'sunglasses picture'. A very close relative of the 'reflection in the goggles' picture and the 'reflection in the mirror/water/window' picture. All of the above pictures are desprate attemprs by the camera operator to appear 'artsy'. Maybe the thought process goes like this.. 'I feel like pretending I'm artistic today. People usually appear artistic when they take a picture of their reflection. This is a good idea, I'm going to do it.'
Other well known generas of pictures are 'the middle finger picture' 'the tongue out picture' and the 'gangsta arms folded all of your crappy ski clothes on at the same time picture.'
