See some of May's most popular photos

Every day, we feature an image chosen from thousands submitted to our photo community, Your Shot. Here are some of the month's highlights.

What lengths would you go to for the perfect shot? Would you brave the Arctic elements to document the northern lights? Dive deep underwater to capture a freediver coming up for air?

The top pictures from last month made me admire the effort that goes on behind the scenes to get a great photo: from researching the story behind your subject to waiting for that perfect moment before clicking the shutter.
