@edgarblythe,
As a young teen, (and indulgent sister), I took my kid brother to a trade exhibition (read new inventions) at the Sydney Town Hall. CCTV had just been developed and screens were set up all around the venue. People were clustered around the site of the camera, and of course, we had to join them. As we stood in the crowd, a woman's shrill voice could be heard saying loudly 'My God! Have you ever seen anything as horrible as that kid? It must be diseased!' Looking up at the giant screen I saw a close up of myself - redhead with a face covered in freckles - picked up by the camera as white with black spots all over it. The woman was standing next to me.
The humiliation was terrible. I refuse to pose for photos, apart from legal necessities (passport, driving licence, etc).
