We've all gotten shots we're proud of – that's why we're driven to click the shutter. But what's the most challenging shot you've ever captured? What's the story behind your most challenging image? What was the end result?
Send us your story and the image you captured (640px on the long edge) to firstname.lastname@example.org
with "My Most Challenging Shot" as the subject.
We're going to share the best stories and their pictures on our news feed over the next few days. We look forward to seeing your submissions!
