Comparisons

An optical illusion makes us see different these photos that are the same, it is the same image, but our brain "interprets" it in another way. They are exactly the same, but someone uploaded it to Imgur, it was shared on Reddit and OBVIO went viral: it is an optical illusion that generates that we see it different even if it is the same image.

Why is this phenomenon generated? The brain tries to perceive the two images as one, so it puts in a different angle to the photo on the right with respect to the one on the left. The phenomenon can be replicated with other images, like the one they shared from the Tower of Pisa.
