I think I'm going to keep it "mysterious". Only going to say that there was barely any post-processing done.Is.. That.. A mirror? Or a hole? I looked for a minute and still can't figure it out.
I love Escher, but didn't even think about him for this one. I did for this one, thoughExcellent example of lines, texture and lighting. Almost Escher-isc.
It looks like a hay-loft in a barn, but I can't figure out why the bottom edge is not straight across.
^^^This, plus a slight tilt of the camera, and voilà!'cause the hole ain't square.
my guess is, that one edge is parallel to the roof, while the other edge is parallel to the ground and hence horizontal.
