The legality under French law of the taking of a picture of someone in a public place without express or implied consent is not clear as a general proposition. With specific regard to the Club O beach, Club O has at a minimum the "concession" for the beach, has it clearly posted as a no pictures space, and there is the obvious nature of the use - those factors create very strong support for public authorities (e.g., gendarmes) to support and enforce Club O's security in acting aggressively to stop picture taking on the Club O beach. What clearly is illegal under French law is publishing any pictures without consent - even if there is no commercial motive. Of course, what good does the illegality do you if you find that someone has published your picture, taken without your consent on French soil, on the internet. I agree with you, Carol, in the real world today, including on the Club O beach, someone could be taking your picture without your knowledge and certainly without your consent. Yelling at anyone walking the beach with a camera in their hand, as I have seen some do without regard to any indication of actual picture taking, will not change the reality.
