You may be surprised.... This was a lesson I learned the hard way - by wasting the better part of a day shooting a wet-weather water fall. I saw it on the side of the road, stopped the car and started shooting - but looking through the viewfinder, I wasn't seeing the reason I stopped. i literally had to stop and verbalize what it was i saw in the scene (the sub-conscience can see it without the conscience realizing it). What i thought I saw was a wet-weather falls that looked inviting - but when I stopped to consider what it really was that invited me, it really wasn't the "falls" as I had been trying to shoot - it was the simple vision of rapid water falling across moss-covered rocks. once I realized that, I was able to concentrate on what it actually was that caught my eye.
