I was struck by the wonderful color and reflection on the murky waters of the Sheepscot River in Palermo, Maine this overcast fall day. Iused a Nikon D 7100 with a Nikkor Zoom elns (18-200 mm.), and a Hoya Circular Polarizer. The ISO was 400, F/18, 1/20th second exposure, and a Focal Lenth of 40 mm. All was attached to a Gitzo Tripod and Arca-Swiss Head.
