Lake Superior Twilight, Ellingson Island, Split Rock Lighthouse State Park, Minnesota. Shot with a Nikon D3x and a Nikkor 17-35mm lens set at 19mm. The image was exposed at ISO 100 at f13 for 2:00 minutes.
Hi everyone and welcome to today’s post. Today’s photograph is another image from the Lake Superior Workshop taken along the shoreline of Ellingson Island in Split Rock Lighthouse State Park. Lake Superior was pretty calm on this day and a few clouds were drifting by towards sunset. Low clouds along the horizon just off to camera left were blocking most of the late sunlight giving a slight blue cast to the overall scene. I have always loved the notion of edges and constantly explore this idea in my images. Edges abound in the natural landscape-light and shadow, earth and sky, earth and water-and it is at the meeting of these edges that photography can be interesting. In this image shoreline rocks give way to the lake environment. Boldly the shoreline reaches its fingers into the cold waters as lapping water rolls over submerged rock barriers revealing a thin defining edge. Beyond this Lake Superior stretches out almost 300 miles and disappears into a horizon of blue sky and clouds.
Technical Details: The clouds were blowing in towards me and with a little filter trickery I could impart a dynamic sense of motion to complement the angles along the shoreline. The camera was set to Matrix Evaluative Metering and manual focus. The white balance was set to 6000K. I used two filters during the capture – a Singh-Ray 4-Stop, Soft Edge Split Neutral Density and a Lee Big Stopper. The Lee Big Stopper is a 10-Stop Neutral Density filter that, as its name suggests, will hold back 10 stops of light. In practice however the filter stops are not precise and it is a good idea to test this in order to get a good exposure. In my case the filter is right on 9-2/3 stops so its close enough. In any event the addition of almost 10 stops affords very long exposures which can impart a sense of motion to the clouds and soften water into a smooth, ice-like surface. The filter will impart a blue cast to the file which can be corrected in post processing. Generally I will preset my white balance up to about 6000K for some compensation but for the most part make corrections in RAW processing.
Thanks for stopping by today.
