A foggy, rainy day in Custer State Park is great fun. Even if you're not shooting, the heightened aerial perspective gives the park a different look. Grace Coolidge Creek flows near a small cave, Hole in the Wall Picnic Area. I liked the look of the fine pine needles on the mossy rocks in the stream, and played with an arrangement of the rocks with a long exposure. I like the contrast from the soft light on the water against the darker rocks, along with the dark green color contrasted with the bright yellow-orange needles and leaves.
