The other day when we were having high winds I noticed this beautiful cloud displaying what's known as iridescence. I quickly grabbed the camera and headed out.
Iridescence in clouds is caused by light waves being dispersed as they pass around extremely tiny ice crystals, with the wave lenghts spead out by different amounts. Therefore the sunlight gets separated into alternating fringes of color. (from The Cloud Collector's Handbook)
But who really cares what all that means? All I know is that it's beautiful.
The cloud hung overhead for quite a long time, shifting colors and intensity.
It finally faded and ended up looking (to me, at least) like a trout rising to take the bait.
