This image, ‘wild light’, was taken at sunset near Loveland, Colorado. As always the colors were absolutely stunning as the sun went down behind the Rocky Mountains.
What is equally cool is the clouds – notice their iridescence.
Cloud iridescence is caused by clouds (usually cirrus clouds like these) that have small water droplets or ice crystals in them causing the light to be diffracted, or spread out. The phenomena is much like the rainbow colors seen with oil in water.
