Frederiksberg Falls

Frederiksberg Park

The only waterfall I could find is in one of our local parks and I wanted a waterfall to try out my one and only filter (that fits - it was the only one in the shop that did fit). Not really sure what it's for - a CIR Polarizing Filter. It's a bit darker and meant that I could use a longer shutter speed and lower aperture for the blurred water thing.

I think I need a lesson in sharpening with "unsharp mask" (which I always do when I reduce for a Blip size) but with 60% more pixels to control I'm not sure that I'm getting the most out of the reduced product. Any ideas or tutorials anyone can recomend?
