Revisiting some shots I took last October that I had previously just skimmed. Fall colors were still a week or two from their peak. I used Nik Software Color Efex to emulate Kodak Ultra Color 100UC film. It added a little punch to the greens.
In the lower mid-left, you can see a lone guy with a camera standing on the rocks. At 1/4 sec, f/22, ISO 100, the falling water is starting to show that silky appearance.
