The 350 mile long Penobscot River flows under the shadow of Mount Katahdin in Baxter State Park, Maine. This image is taken about a mile or so from the Abol Falls Bridge along the Golden Road. I had to climb over several large boulders to get to a place where I could see both snow-capped Katahdin in the background, and have an unobstructed view of the flowing water. I really liked the blaze of color that the fall foliage offered on the nearest river bank to the left. To slow the water and get the misty effect in the foreground, I used a 6-stop neutral density filter that allowed the shutter to be open for 15 seconds.
Technical data: f22, 15 seconds, iso 100, 17-40mm at 20mm with a 6-stop ND filter.
