This illusion is from a very old
newspaper cutting though the same illusion (or variants on it) appears in popular
publications today. The caption invites the reader to guess which elephant is bigger...but this is an illusion: They are all the same
size. If you don't believe it, try measuring them with a ruler.
The illusion makes use of two devices to suggest distance - the
perspective lines receding to a
vanishing point and the use of shading. Because these features cause the eye to think that the darkest
elephant is nearer, we assume it will appear largest. The fact that the lightest shade of elephant appears larger
fools us into thinking it is actually a bigger elephant.

Which red circle is larger?
They are both the same size.
Explanation
When we look at a two dimensional object, our eyes automatically try to convert it to three dimensions, because we live in a 3D world.
In this optical illusion, since the upper tire (gray circle) is smaller, we assume it is farther away than the lower tire. The inner white circles are the same size, but since the upper white circle covers, proportionally, more of the gray area, we assume it is larger.
Variations of this type of perspective optical illusion are very common.

The top object appears to be
smaller then the bottom one but they are actually the same
size. Move the top
shape over the bottom to see that they are the same
size.
They are the same size but the short edge of the orange one is
compared to the longside of the red one. Therefore, the red figures looks as if it were longer.

In the traditional presentation of the Ebbinghaus illusion, two central circles are of the same physical size appear to be different sizes as a result of the context circles surrounding them. Which central red circle looks larger?
I hope you answered that the one on the left looks larger, but what if I asked you to pick up each of the two central circles? Would your reaching movement betray a susceptibility to the illusion?
Actualy those both red circles in middle are in same size.

The ink’s density in the left figure makes it appear larger than the right, when in fact they’re the same
size. From a German/French magazine. Translated:
When you lay the figures next to each other in the same direction it appears that the one in front is bigger. Both are really the same
size. Cut out these figures.
