The church has "judgement gate" an old Roman/Herodian gate, onto which the gate of the Holy Sepulcher was built, so it has the largest archaeological remains of Constantine's original church. There was a nun praying there, intensely chanting and occasionally bowing. So I set up my tripod and camera and went to work. I took two 360 panoramas, and several dozen other pictures of everything of interest, all the time taking care not to disturb the nun in her prayers. After about a half an hour of photography, the nun stopped her prayers, looked and me, and said, in Russian, "you can't take pictures here." Considering I was actually done photographing, I didn't object, but was quietly expelled. I don't know if the nun was so intense in prayer that she hadn't noticed me, or if she was annoyed for a half an hour, but refused to stop her prayers to throw me out. At any rate, because of her intense devotion, I got to take all the pictures I wanted before being expelled.
