In France a photographer has to have written autorisation from the person photographed to publish his image. Without this the photographer can be sued for damages.
A man and a woman were photographed together in Parisian street at 10 o’clock in the morning. Following publication the man’s wife discovers that he has a mistress and his employer sees that he wasn’t at work that day. He is fired and his wife files for divorce. He then sues the photographer. If this man had taken the trouble to put a mask on that day he would have had a lot less trouble.
