I thought I might have a decent illustration of this with two photos of the same car. This first is from about 5' away max with a lens setting of about 35mm.

This next one is from much further away with a lense setting of about 100mm.

You can see that the car looks quite different even though it is the same exact car. I don't know why the color looks different, but it's basically from different lighting. But look at the front bumper. It looks very rounded in the first shot, and very flat in the second. Look how much more of the fenders and side-view mirrors you can see in the second shot.
Hey, why would image code be disabled in a forum about photography?
