Well, people disagree to the extent to which a single photograph represents "reality", but there is something to be said for the idea that a single photograph at least captures a single moment in time. Or if you can countenance the idea, sometimes an "extended moment"
What seems odd and slightly sinister to me about this particular example is that, without the photographer's intervention or choice, a moment in time has been manufactured.
Of course, if you see any photograph, whether printed or on a screen, created from whatever original medium, you have no idea whether that photograph has been manufactured in the same way. Naive as it may seem to us now, the debate that raged around the Cottingley Fairies demonstrates that fakery is not new in photography.
Nevertheless, I still find it all a bit peculiar and dystopian
