This shot of Rattlesnake Falls in the White Mountain Area of Northwest Arkansas is currently my favorite shot. You can see it on my Flickr page here where it looks better for some reason.
I used a neutral density filter and a polarizer to get a slow enough shutter speed to make the water go all blurry. I worked up the pic in photoshop using some skills I picked up from Scott Kelby’s 7-Point System for Photoshop. It’s a great book. I recommend it.
