We are supposedly taking trillions of pictures now according to experts who calculate such things. If we eliminate selfies from that count, I suspect the remaining images would total about six. I exaggerate to make a humorous point. Seriously, there'd be about eight. This tsunami of selfies exhibits a cultural narcissism that is breathtaking. I'm slightly frightened by the long-term implications of all these selfies. It seems to me the photography's greatest gift to humanity is its ability to concentrate our attention on others and the fascinating world we inhabit.
