Imagine there is an artist with an eye condition that caused him to view objects as elongated. If he sees an apple, it appears stretched to the point of being oval, whereas to you and me it appears as a normal apple.
You walk into his studio and see that all of the paintings mounted on easels feature everyday objects. The strange thing is, you notice, that all the objects featured on the canvasses look stretched and elongated.
Is there supposed to be a picture or something attached, or do we just have to imagine it? The answer to the question is no though - if his eyes were knackered in such a way then how would he find the canvas to paint on?
You have to imagine it I'm afraid. The answer is indeed 'no'. But for a different reason. He can see perfectly clearly - objects mearly appear stretched out from his perspective...
