Anticrepuscular Rays point westwards at dawn in Templestowe, Victoria, Australia. Caught by Keith Webb.

 Crepuscular and anticrepuscular rays and shadows are essentially the same phenomenon. They are long parallel shafts of shadowed air with sunlit air between them. Perspective effects alone make them appear to converge on the sun and antisolar point respectively.
