“Eggs are round”. A fake egg made to mimic a real egg is chosen as the basis and photographed to become a two-dimensional image. Since the egg itself is not an ellipsoid that is absolutely round, in order to make the egg absolutely round you need to reverse the two-dimensional paper distortion of the fake egg image by utilizing the three-dimensional space in a near-large-far-small way. The egg image is then photographed in reverse perspective to make the small outlines larger, ultimately making the egg image close to the shape of an absolute circle.
