I don't know if it could help in the question, but I will state some informations about me:
Nationality = Italian
Residence = Germany
A week ago I was in Thailand and took some photos of performers during a dinner with show. It was not possible for me to make them sign any paper about copyrights etc.
My question is: was the performance "public" (we were after all in a restaurant, which I believe was a private place) and if so who owns the copyrights? What can I cannot do with those pictures and which law should I obey to (Thai, Italian, German)?
