A mind-boggling optical illusion of a man taking a picture at sunset has left people online very divided over which way he is facing.
The image, posted to Redditt, shows the man's silhouette, but people can't tell if he is facing the front or if he has his back to the camera.
One commenter said, “Wow, this is a really good one. I can swap it back and forth and still can’t really decide which is correct.”
Someone else added, "I showed it to my wife across the table and seeing it upside-down breaks the illusion, and I can only see it as facing away in that condition."
What do you see?
