As a photographer I have always found it extremely hard to photograph people in the streets. I come from a country, Morocco where it is very much frowned upon.Or it was.there is also a discrepancy between the ractions if it is a man, a woman , a tourist that takes the picture.
In the south, and countryside some people belive having their photo taken takes their soul.Their reactions can range from fear and run to agression.
It has scared me from an early age.I dont count the times I was verbally abused.
In China for the first time, I managed to make some decent people photos.
