Circular Supernumerary Rainbow

Back in June, I was in Detroit with my wife and kids, and the weather was right for rainbows. We got lucky, and came across this lot which was mostly covered in puddles, and it provided a perfect reflecting pool. At the time I did not know how to process HDR or fusion, or tone mapping, but my friend Ray had taught me how to bracket pictures, so I was doing that from time to time in anticipation of future processing.

 

I originally posted a picture of this rainbow and reflection in June, but have gone back and re-processed it based on what I know now. I hope you don't mind the re-visit.

 

A supernumerary rainbow—also known as a stacker rainbow—is an infrequent phenomenon, consisting of several faint rainbows on the inner side of the primary rainbow, and very rarely also outside the secondary rainbow. Supernumerary rainbows are slightly detached and have pastel colour bands that do not fit the usual pattern.

 

If you view it in the largest format, you will see the supernumerary effect.
