I have a firm, long-standing rule of NO PHOTOGRAPHS to be taken of me by anybody, anywhere, and I enforce it. Sometimes odd situations arise...
When photographing my niece outside the school in Beijing where she was assigned for a week, a crowd quickly appeared around us, left right and straight in front of the camera (!), and oddly, not a single person I looked at had a camera in the proper sense, but all smartphones (even very young children!). On this inauspicious occasion, I was cheerfully unrecognisable amongst the dull, grey and freezing landscape: my entire face was covered with a silk balaclava, a thick beanie on top and yellow-tinted glasses (to increase contrast). In essence, the clammering, rugged-up masses saw a (faceless!) photographer, dressed no differently to the millions of other residents of Beijing seeking protection from the bitter weather. In a land obsessed with technology, witnessing a real camera for them (I did not see any cameras during localised travels) must have come as a revelation, to say nothing of the loud whack of the shutter going off, which had the neat effect of sending them packing and the cheery, toothy-grinned students back to class!
