Photography: Cloud Art

By Kevin Ambrose

Have you ever seen clouds that race across the moon at night? On the night of Feb. 20, clouds from a departing storm system moved quickly across the sky as the full moon headed toward a total eclipse. I had fun playing with timed exposures that night, using the clouds to both dim the eclipsing moon and also paint streaks of light and color across the sky. The photos I originally published in February were just a few of the total that I snapped that night. Keep reading for more photos and explanation.

Basically, I just waited for a fast moving cloud to approach the moon, then I set off a six second exposure as the cloud moved across the moon. During the six second exposure, there were times when the moon was completely visible, other times when it was completely obscured. The photos show an average of the light during those six seconds, with the darker cloud details hidden in the photo, but with the light that had illuminated the clouds visible on the photograph.

I was pleasantly surprised with the results, especially since it was not a planned shoot, but more of an experiment to help kill time as I waited for the eclipse.
