The photo of this bridge was taken at the beautiful Cuyahoga Valley National Park located in Brecksville, Oh as I was leaving from an awesome day of shooting Waterfalls :)
I used the Fotodiox Wonderpana Free Arc System with ND 16- 4 Stop Circular Filter and my new Nikon D 610 mounted on a Mefoto Carbon Fiber Globe Trotter Tripod :) This is 5 exposures 5/10/15/20/25/ seconds blended into 1 Image
