The video was shot on approach to her home/shack from the helicopter (which was a ways off). I called my dad to see if he can locate the video somehow (my grandfather passed away several months ago), and I'm trying to find the book he wrote which touches on this experience.
This is vague recollection at this point, but I do believe that the family did have knowledge of photography (my grandfather visited her 10+ years after this family became 'famous' through Russian press) and the father did not approve of their pictures being taken at first. I can see how that, combined with their deeply religious and isolated world view, could have been a cause for her superstition.
