There are very few waterfalls in the world where Moonbows regularly occur. The waterfalls have to be oriented in just the right direction. And a full moon must be in place.
Cumberland Falls in Kentucky is one of those places. Last night we dicided to pack up the gear, drive the approximately 80 miles, and see if we could get lucky with the light. There was a pretty good haze in the air, and we had pretty much given up on seeing the moonbow. But as long as we were there we took some night shots of the waterfall. The exposures were 5 to 15 minutes, depending on ISO and aperture. After all, these were taken between 9:30pm and midnight.
Here are a couple of the night shots.
Just as we were about to pack it in, the haze cleared and the moonbow was visible. With the camera the colors are captured. With the naked eye it appears more as just a light colored arc, without the distinctive colors. And with the long exposures, the background is definitely lighter than the eye really sees.
All in all, a good evening.
