Whether it’s a sunrise or a sunset, for me, it’s the clouds that make the scene worthwhile. This same setup with clear skies would be pretty bland. If you can add the silhouette of a lighthouse and the sun’s reflection off the water, all the better.
Even though I’ve photographed the sunrise over Lake Michigan near the Kewaunee, WI lighthouse many times before, it has never looked quite like this. In every case, the clouds make the difference.
