Upper Tahquamenon Falls, in Michigan's Upper Peninsula, from a visit a couple of years ago.
I took several different exposures to see the effect on the water movement, with times ranging from 2 sec to 15 sec. This was the 15 second exposure, and my favorite.
I should mention that I did bump the saturation in the oranges and yellows a bit in the trees, but the orange in the water is very nearly this color naturally, due to copper and minerals in the water in this area.
I tend to bump up saturation and contrast... vibrance, too. I just like the look. This is a great photo... nice balance of fall color, and the streak of orange water from the mineral deposits is a neat contrast.
Thank you very kindly, Cathleen! I appreciate the comment!
