Why "the tilt shift?"

While perusing the internets, I came across this Tumblr called "Dictionary of Obscure Sorrows." One of the entries was "the tilt shift." I feel it describes the content of this blog perfectly.

the tilt shift

n. a phenomenon in which your lived experience seems oddly inconsequential once you put it down on paper, which turns an epic tragicomedy into a sequence of figures on a model train set, assembled in their tiny classrooms and workplaces, wandering along their own cautious and well-trodden paths—peaceable, generic and out of focus.
