Mirror exposure On the left is a normal photo of President Obama. On the right is that same photo reversed from left to right. To you, the photo on the right might look odd. But to the president, it probably looks just fine—in fact, if he is like most people, he prefers it to the one on the left. Whenever Barack Obama looks into a mirror, he sees an image like the one on the right. Mere exposure effects would result in his liking it more.
