Looking happy in a photograph is a tall task for many people. But don't worry, because this little video will teach you how to look naturally cheery whenever somebody points a camera your way.
Rule number one: Don't say cheese. Ever. Instead, you should say something that ends in an "uh" sound. But there's far more to it that that, so take a watch. The camera will love you for it. [YouTube via Laughing Squid]
