Snow Creek in the national forest.  Iīve know how to blur moving water forever, but Iīve never actually done it before.  ISO 50, F/22, polarizer filter to cut down the light a bit, I was able to get shutter speed down to 1/3rd of a second with this one and slower with some of the other images.  To get even slower I would need to get a neutral density filter.
