Sky Replacement
Replacing the sky and modifying the toning of the image made a huge difference to an otherwise lackluster shot.

This Los Angeles hotel was photographed on a clear afternoon / early evening. The sky was a deep blue, without a cloud in sight. I framed the shot with the puddle in the foreground to give some sky reflection. In the after image I added sky replacement, and worked the toning to match the darker hues of the clouds.
