Stuart, you have captured lovely fall colors. I like the diagonal line of the waterfall. It appears you used a slow shutter speed to get the silky water. I would like to see all of the lower cascade.
This is a spectacular waterfall! And you framed it very well with the trees in a nice array of greens to reds and yellows. Would you share the exact name and location of this? It looks like a wonderful place to photograph, and especially in the fall!
