Comments: Originally, this wasn't a very good image, as the sky was a little over exposed and washed out as I'd metered for the darker buildings. However, a quick adjustment to the levels in Photoshop has produced something a little more interesting - backlighting to the buildings, and some intensity and colour to the sky. I could have kept the levels unadjusted for the buildings to keep their detail and increased the saturation for the sky alone, but I think the photograph has become more atmospheric as a result of the silhouetting and increased contrast between the lit and shaded parts of the buildings.
