This incredibly short-lived moment was going on while I was poised and ready for the sunset on the opposite side. A rain cloud passed overhead and the lens caught droplets, but I thought to follow it as it passed over the dunes.
Sure enough, a double rainbow started to emerge right after it. I rushed to get my feet wet and get knee-deep into the swirling see and weed. Which might be a fun foreground subject.
What I personally like most about this scene isn't the rainbow, but the gold-colored, translucent rain illuminated by the last light of the day.
This moment lasted for no more than 20 seconds. :)
