Airbrushing Water

When in a high school photography class I learned long how to photograph water to make it look like it had been airbrushed. When I switched over to digital I could not remember how to do the technique. With my recent jaunts into photography technique books I ran across an explanation on how to recreate the effect. While in Oregon visiting my sister I took advantage of the many spring waterfalls to practice the technique. Since I tend to 'freeze' water motion (I like the ice effect) I decided to play with the water motion and try to capture different feelings of motion rather than simply frozen..... don't know if I was successful or not ;o)
