Details:
This was a beautiful sunset enhanced by volcanic aerosols creating the purple twilight, but here punctuated by two shadows cast across the sky (crepuscular rays) diverging from the sunset point and likely created by distant storm clouds over the horizon to the west. It was one of the best displays of crepuscular rays I'd seen locally. The image is a 3-exposure High Dynamic Range stack, each exposure 1-stop apart, to record both the darker ground (a field of yellow canola) and details in the brighter sky. Taken with a Canon 5DMkII and a 16-35mm lens.
