The above is a low view of the cascading fountain near downtown, taken right at dusk. The fountain has been on my short-list of “things to photo” when downtown, but I’ve wanted to work the long exposures later in the evening or at night to get more interesting colors in the water. This turned out to be a fun, and somewhat surprising exercise in light. As the sun dropped behind the buildings to the left, the neons and street lights became the dominant light, transforming the color of the scene entirely. And once it was full on dark, the color changed dramatically again because directly behind me is a river lined with riverboats and casinos that cast their own hue into the water.
As for the image, it is only one exposure…but…the original had blown out the sky a bit. In post, I made a copy of the original .raw file, but set it a 1 ev down from the original and used the recovery slider a bit to pull back some highlights. I then fused the darker & lighter exposures in Photomatix.
