If patience is a virtue, National Geographic photographer Steve Winter has a lot of them. Wildlife photography always takes some waiting—but 14 months worth? That’s how long it took Winter to set up the shot that he had been envisioning: Downtown Los Angeles’ wild mountain lion in front of the Hollywood sign.

Winter spent 14 mounts tracking the mountain lion’s patterns, then looking for spots where the location is immediately recognizable as urban Los Angeles. Since the lion hunts at night, he worked with Nat Geo’s Remote Imagine engineers to construct a special system that uses both infrared detection and external lights.

Here’s how Winter got the shot.
