This picture was shot on a tripod with three exposures (-2..0..+2EV). I used Photomatix to create the HDR with tonemapping and detail enhanced. I decreased the overall saturation with Hue/Saturation in Photoshop. Curve adjustment to increase the overall contrast. Unsharp Mask to increase detail on the moss and the rocks.
Along the way to Multnomah Falls, we stopped at Wahkeena Falls to test out my ND8 filter. I shot this at f/8.0 and the ND8 filter gave me an extra 3 f-stops. This allowed for longer exposure time to get the silky water flow. Of course, I did my 3-exposure shots to process this in HDR.
