This was my first attempt with ND filters. It was a 34-second exposure with the B+W 10 Stop ND filter. This building is located near 183 and Mopac and is currently under construction being rebuilt from when that guy flew a plane into it about a year ago. Good to see it finally coming back. I plan to do a lot more experimenting with these ND's soon, including some at the coast this weekend. I have this 10 stop one and also a 3 stop, thinking about maybe combining them for even longer exposures? Processed with Photoshop CS3 and Photomatix Pro.
