I knew I couldn't do much in the way of slow with all that light, but thought this bridge leading down to the river and the dam in the background came out nicely. Did smooth the river some and blurred the dam gates nicely while keeping all the detail on the bridge fencing Shot at f/36 for 1/10 sec ISO100. Not an area I can get to safely at night and wanted to try it.
I like the leading lines, the water does look smooth. Cybelle is right, an ND filter (or a set) will give you lots of new possibilities, lots of detail, very nice
