Abrams Falls...Shooting Waterfalls

I used a 9 stop Neutral Density filter so that I could get a 45 sec. exposure. Long exposure gives you that silky water and smooths out the splash pool. Normally, I would have been there before daylight and just used long exposure alone, but this falls is located inside Cade's Cove and the rangers don't open the gate until daylight. It's at least an hour walk in and by that time, the sun was up fairly high making the scene too bright. Intended to do a video there this morning on how to achieve the effect, but the waterfall was so loud, I couldn't get decent audio even with a $300 Rode Microphone. I will have to shoot that video at a quieter stretch of water and I will post a link to my youtube channel when I get it posted.
