While I don’t recall if there were “no flash” signs I would think there must be.
I am not much of a photographer- mostly use my iPhone (no flash) while traveling/touring. I would think most photographers would be aware that flash is not to be used in places like that.
My purpose in posting this was to let others know of the change in policy. Many might leave cameras at hotel when they visit the Borghese, especially if they are not comfortable with checking expensive equipment. I appreciated being able to keep my iPhone in my possession and snap just a few pics.
That said, we were shocked at the number of tourists taking photos in locations that were clearly posted “No Photos”.
The need for some people to take a selfie (usually in a silly pose) in front of holy altars, etc was especially annoying and incredibly disrespectful. Just as bad as those who don't know the meaning of Silence, Please.
But I digress…
