I would like show you test hdr studio which I've made on my project created during amination training in PlatigeImage


I use same tric - I set HDR map standard in luminosity 100-400% and add one copy of it as a layer to transparency on normal/invert 100%, but invert and second layers, but on additive/invert over 100% (I set 110%-1500% - depends on scene)
It works like a lens, byt it has to be use Psychical Sky or Light Map in the background LW. Effect not working when Becground is black!!!
One more samples of those effect on project dyspenser created for Panasonic.
