The polaroid thing is super easy to explain, the polaroid has a default setting to use the flash and focus on things a few feet away, his other camera has the flash off and more of an infinity focus. So the polaroid will not pick up the light in the hallway no matter how much one might think it should (yes, I use polaroid cameras, old and new).

A person who knows polaroids at all would know this, which does make me start to think this is somewhat contrived.
