Last night was remarkably clear, and I was able to spend some time on a beach near my sabbatical home in Lorient, on the west coast of Brittany, France. The image shown below was constructed from numerous frames starting just after sunset. I added ballast to stabilize the tripod, and the results are satisfying. This is a view from the beach, looking southwest at the Atlantic ocean. The bright green light is a lighthouse on the nearby Isle of Groix.
The image was produced using a Canon EOS 60Da with an EF 28mm f/1.8 lens. It is a manually blended panorama of three segments. The bottom segment is a single long-exposure shot taken just after sunset. The middle and top frames are long bulb exposures at f/4 using an iOptron tracker. The frames were HDR stacked using six frames for the middle and upper segments with varying exposure times. Most frames are at ISO 400. Some frames at 800 and 1600 are also included in the upper two segments. It became progressively darker when the upper segments were taken, resulting in a “glowing atmosphere” effect.
