Privacy is of great concern in the UAE so be sure to take images of locations and not people. Even then be aware of what you are doing. As an example my husband does a lot of work in the UAE and was invited to assess a super yacht last time we were there. He thought nothing of it and took photos of the boat for the purpose of quoting the owner. When we left, at the airport he was taken into a room and made to explain the photos. He had all the contact info of the owner and could supply info that supported his request to be there, but even though they were really nice about it, the time it took meant we almost missed our plane.
