I ended up at this river quite randomly early one foggy morning. The photo was taken in the fall and the colors in the front tree are quite vibrant. While editing, I decided to try a red filter over the photo and I felt it really brought out the warmth of autumn color. It added an interesting look to the reflections on the smooth river as well. This was taken in British Columbia, Canada.
