A passing cloud at sunset in Lisbon

I took quite a few photos at the 25 de Abril Bridge, as it was the best weather I had during my Lisbon trip. But since I enjoy photographing bridges, I probably would have taken many shots here either way.

For this one, I noticed a huge cloud moving quickly in from the side, just as the sun was dipping below the horizon behind me. So I set up my shot and waited for it to catch some color, and it did. For a brief moment, even the composition came together nicely. Not long after, though, the cloud moved on, leaving an empty space above the bridge, but by then I already had the shot.

This photo is a blend of two exposures in Photoshop, taken with a 17mm tilt-shift lens.
