Tbf that could have been done by tenants who figured the landlord would use that damage to argue they should lose their entire deposit despite not costing nearly that much to repair properly.
Not that it wouldn’t be plausible that the landlord did it themselves or hired someone who didn’t know what they were doing but were willing to do it cheap, like Ricky.
For depth of field, our eyes don’t automatically do that for a rendered image. It’s a 2d image when we look at it and all pixels are the same distance and all are in focus at the same time. It’s the effect you get when you look at something in the distance and put your finger near your eye; it’s blurry (unless you focus on it, in which case the distant objects become blurry).
Even VR doesn’t get it automatically.
It can feel unnatural because we normally control it unconsciously (or consciously if we want to and know how to control those eye muscles at will).
