Here's something I can do with my new Nikon that I can't do with my smaller cameras - blur the movement of water. The slow shutter speed necessary meant that overexposure was a huge problem with my Panasonics (and you can't get grad filters to fit either of them). But I'm pleased with this, my first DSLR attempt at a nice soft waterfall. I haven't any filters yet but it worked OK without. I was amazed at the duck, which stood calmly preening its feathers in all that rushing water and never seemed to get swept off balance. Perhaps it was stuck!
