That's not even tilt shift (which would imply some deliberate effort )... the doofus just used the portrait setting on their phone which is meant to frame a face not a detached garage lol
Definitely software based blur and not tilt shift. Some close up grass, the shed, and the distant neighbors house are all in focus. The only optical way to do anything like that is throwing Vaseline on only certain parts of a lens filter.
Also to note, this is my favorite Lemmy community by far.
