You must have seen pictures, paintings, games related to optical illusions. They are fun. Aren't they?

Optical illusions are all about light, how it reaches our eyes and how our brain interprets them. A lot of physics is involved in understanding them.

You can think of many optical illusions made by man. But there are quite a number of them found in nature too. Some are interesting and some are unbelievable. Some are easy to be explained and some are hard to believe even after the explanation. You can call them pranks on us by nature ;)

Italian photographer Barbara Scerbo is no illusionist but she surely knows how create one using her photography skills.

Scerbo has recently created an illusion-based photography series, called 'Illusion'. In this series, Scerbo has shown the subjects with their limbs and bodies crawling out of a mirror that perfectly syncs with the background -  the landscape and the surroundings, creating an illusion that the subjects body is see through.

These optical illusions are just amazing and brilliantly put together.

Sebastian Bieniek is a talented German artist and the brain behind the 'Doublefaced' photography series that these days can be seen all over the internet. Why, all because of its unique theme.

This series features a doublefaced German girl. Not that there is in actual a two-faced girl in Germany but Bieniek using simple makeup products like eye pencil and lipstick has created an illusion and for a moment it actually seems like the girl is two-faced. (Even I got confused for a few minutes.)

If you are reading this and you loved Erik Johansson's surreal photo manipulations when we last featured his work on our blog, then you're in for a treat.

Erik Johansson is a full-time photographer and retouch artist based in Berlin. He does both personal and commissioned projects and his illusions are amazing, more than one look types.

Erik was born in 1985, outside a small town called Götene in the middle of Sweden. As a kid he loved both drawing and playing computer games. He got his first digital camera at the age of 15 and that has made the difference.

Erik never like the end results of capturing a photo through a camera, as it was no creation. Because of his interest in computers he soon started manipulating the photos, he captured and after that he never looked back. Everything that Erik does, he has learnt it himself.
