Despite the fact that we depend on our vision more than any of our other senses to understand and navigate the world, it is also the sense that is the most easily fooled. This has led to the huge popularity of optical illusions that take advantage of the shortcuts and tricks that the brain uses to interpret the data it receives from the eyes. Such illusions are not just something that have originated in modern times either, the advent of photography in the 1800s meant that even those in the past could create strange and sometimes haunting optical illusions.

If all artists could do this, it would make self-portraits far easier to paint.
