Chicago downtown from North Beach. I took a long exposure shot from the same location before www.flickr.com/photos/smik67/6012115490. I waited for this wave to provide a leading line to the downtown and help the composition. Also, in this shot, the sunrise color reflections off the citiscape is more prominent than the long exposure shot I took earlier.
This is a single shot (not HDR). In order to expose the sky correctly, I used a Hitech 0.9 reverse-Grad ND filter using Cokin holder.
