Thank you for your prompt reply, which is most helpful.
The situation is as follows. I currently work for a UK author, who has commissioned photos to be taken in Paris, some of which we took inside some of the cafes. I
did contact the owners of the cafes in advance of our journey to make sure we had permission to shoot inside their properties, but only one of the owners replied saying he would get back to us as soon as he was back in France.
We went to Paris in the meantime and took the photos without any problem whatsoever. We have also went through the trouble of avoiding any direct photos of people's faces.
Now back in the UK the publisher - which is a major publisher - is telling us they cannot publish the photos without permission from the owner and the people inside the cafe.
They are also telling us that only photos shot outside the property can be used. I am not aware of French laws, nor of any bearing they could possibly have in the UK.
Are there any grounds to such claims? What is the book's later editions are published worldwide, or sold on amazon for instance?
