Long Exposure Photography

Just ordered a B&W 3.0 nd 1000.  Cannot wait to delve into the possibilities of a 10 stop filter.  I have always been attracted to long exposures but have been limited in my experiment to either night time shots or small apertures.  Not any longer.  Since I am going to have trouble waiting for the Oct 22 delivery date I will be soliciting tips and tricks from my fellow photographers that use long exposure.  

So it makes sense that the feature would be about long exposures.
