There are special agonies that are reserved for the "official photographers" of families and friends. One of them is when you sprint into the scene after setting your camera's self timer, only to have the camera snap the photo before you're ready. It was even worse in the days of film, when sometimes you might not even see the blooper until after the photos are processed.
Above is a family portrait that captures this pain perfectly. It was shared with us by a woman named Molly, who says it's her favorite photo of her father, Geof -- he's the one that set the timer.
