I am curious how you arrived to "fake" as conclusion where there is absolutely no sign or reason for faking anything.

I think that it is obvious, to casual observers as well, that this is a modern day photographer using vintage equipment. No need to resort to detective work to notice the obvious modern wiring (which is present in every picture except for one, the elephant), or that the author is still alive, when that information is just in the captions.

And the reason why it's done is obvious, too: It's a great artistic choice that meshes well with the subject's aesthetic.
