Why Camera Nerds Can Be the Worst Nerds

There's so much one can learn about cameras, from ISO to white balance to aperture settings. And there is, for some reason, an irresistible urge to share that knowledge once you've learned it, even if no one's asking, and even if it's totally irrelevant to the conversation at hand.

I love you, camera nerds. But my goodness, you can be annoying. [xkcd]
