I grew up a few miles from Taughannock Falls and it was always difficult to photograph since it is in the shade on sunny days. I thought HDR would be the solution, but unfortunately had an overcast day each time I visited. This one in late (yes late) spring, is a very interesting image nonetheless. And some of the nearby dark areas serve to increase the dynamic range.
