Thank you all.
I very much appreciate your comments so far. In response to some of your questions; I was inspired by two entirely distinct elements from which I accidentally found a new path to treat either natural or artificial light. The first element concerned a phenomenon known as the Brocken Spectre (Ghost) which arises if you stand on a summit and the sun throws your shadow on a cloud below. If the conditions are right, you may see your shadow with a saintly rainbow-coloured halo around its head.
The other element that inspired me is the work of a prominent Australian photographer Sonya Payes The Iceman as you can see for example here The method she uses to control the light and the reflection really left me with a great impression, I admit.
