This HDR photo of Blue Hen Falls was taken at the beautiful Cuyahoga Valley National Park located in Brecksville, Oh.
I used the Fotodiox Wonderpana Free Arc System with ND 16- 4 Stop Circular Filter with a Rectangular Sliding 2-Stop Grad ND filter and my Nikon D 610 mounted on a Mefoto Carbon Fiber Globe Trotter Tripod :)
This is 5 exposures 5/10/15/20/25/ seconds blended into an HDR Image. :)
