Another thought. If I was going to a Church and was going to take photos, I would ask reception if it was OK to do so. I might be a bit old-fashioned in these days of cell phones with cameras, but when I go to a museum or such, I check if they are OK with pictures being taken, and it would be the same for a Church as they might not like photos being taken of parishioners as religion is a private matter. Just saying.
