Okay, I'll take a guess but probably wrong, but it's all I can think of... The background. The right side shows the bricks more in focus, while the suit on that side is less in focus. And the bricks on the left side are less in focus, while the sleeve of the suit is more in focus.
And that's just a complete guess. My other is that he is just way too young and handsome! LOL! :-D
