2616. For example, if one does a drawing of a pear and the pear in the drawing is about 2 percent wider than it actually is in real life, no one would ever notice it. If one looks at a drawing of a pear that is slightly out of proportion one simple takes it for a different pear altogether, or perhaps a different variety of a pear.
2617. If an artist draws a Bartlett pear, it might come
out looking like a French Anjou pear; so too with a drawing of an apple.
A drawing of a Macintosh apple might come out looking like a Delicious
apple and no one would know the difference. A botanist might notice the
difference, but even so, they would probably not make a fuss about it.
2618. This same lack of perceptual differentiation can be
extended to almost anything except the human face. A dog’s snout can be
too long, and so we see it as simply a different dog, and a picture of a
chair can have legs that are too long, and a giraffe can have legs that
are too short and nobody will notice the mistakes because we just take
it for a tall chair and a short giraffe, and not a bad drawing.
2619. But just try to paint a successful portrait of somebody’s grandchild. Do your best and exert your utmost skill but you will fail! This is not to say that the Grandparents in question will not love your painted portrait and praise it at length but you will be able to detect in all that praise their obvious dissatisfaction with your efforts.
