When a foreigner visits such place(being pilgrim or visitor only) the need to take photos is active.There are many holy places where to take shots is free of charge or a small tax is asked.At Bachkovo,all shots are prohibited.There are many observers-not only monks-who stop every movement which could mean to photograph.Of course when the camera is a big one,to move gets harder.when I took this image which shows you a quiet place with a nun of Missionaries of Charity Order visiting this place,there was a monk behind me,on the floor,who cries at an civil observer to watch me carefully (they didn't know I understood Bulgarian a few). My first impulse was to shot both of them looking and crying at me but my wife strongly opposed, reminded me that our goal was to pray.I don't dare to advise you about taking shots in such conditions but,however,I tell you what I did:didn't lift the camera to the eyes,discover the observers or surveillance cameras,take a distance from them because the noise of camera could be detected,use a remote control from the pocket,use a wide angle lens.If these are not enough then a mobile phone is a good help.
