The lights, sitting on the Canadian side, cycle through a range of colors. A typical resulting image of the American Falls is:
So, now, many are saying to themselves some assortment of "ooh" and "aah". I was pretty happy with the result that night. But, I recalled a previous time when I walked to the falls in the very early morning when the floodlights were off. So, I got up and was there at 6:00 am. The only light was the ambient city lighting reflecting off the low clouds. Here is what I found:
Absent the strong floodlights, the foreground colors come out nicely and the textures are better. A vertical image absolutely won me over to the early morning result.
So, you might say that I was reminded of Keep It Simple, Stupid. I know the floodlights attract both moths and tourist alike, but predawn is uncrowded and beautiful in a simpler way. Another bonus was that the wind had subsided and it was definitely easier to keep my hands warm.
