Reuters photographer Kai Pfaffenbach found himself unexpectedly on the other side of the lens at the IAAF World Championship Men's Shot Put Finals. His photo of Germany's David Storl was used as evidence in a decision that overturned a 'foul' call and awarded the athlete a gold medal. When it was called into question whether Storl stepped outside of the ring in his attempt, Pfaffenbach discovered that his image from a remote camera clearly revealed Storl's attempt to be fair. The attempt was ruled valid, Storl was awarded the gold medal and Pfaffenbach received a great deal of thanks from the shot putter.

Pfaffenbach's camera was in the right place at the right time, but only because he'd been trying to get a particular shot of the action. He was on the verge of deleting his photo when he noticed that Storl's throw was in question and came to his aid. In other professional sports, cameras have been installed to provide final ruling on questionable plays. England's 20 Premier League football stadiums have all been equipped with goal-line technology, and though the season just started last weekend they've already been put to use. While American football has yet to adopt anything quite like that, network TV coverage this year will take advantage of endzone multi-camera rigs just for fun
