Hi Eric - I haven't heard of this very interesting technique for water. So am I correct in understanding that you are selectively blending multiple 2 sec water exposures to create one image with smooth looking water surface that also has texture (as opposed to water that looks completely smooth and almost featureless as a 30 sec exposure might produce)?
