Here along the South side of the Erie Canalway I came across a dam and spillway with valves. It seems to regulate and keep the Erie Canal at a maximum height by spilling any excess water over into a creek.
In the first view you can see the pre-HDR image or jpg as it came out of the camera.
The HDR view below it is not altered or enhanced in Photoshop as it is just a merging of 5 images of the same scene of different exposures combined in Photomatix software. This allows the larger spectrum of light to be seen much as the human eye would see it there at the time of capture.
