Mmm. Yes, the Queen is a good one, as she has been one of the few famous people photographed all through the progressions of photography over many decades - what I mean is, she started being photographed when comparatively few people had a camera, right up to now when lots of people take photos on mobiles, AND she's been similarly treated in many countries of the world.. ..AND often photographed many times over by the same people on every occasion they have seen her during her/their lives....that's apart from the official and paparazzi news photos. Then there's the newsreel films, the videos .... !!! Other people I can think of were photographed a lot for a shorter time and often the same photos of them were used over and over. Also ordinary people wouldn't have had access however long they had lived. The Queen appears in many photos taken of other people- her family, visiting dignatatories, etc. wellhungjock has got it I think.
