Ah, that explains a bit of what I've been seeing in conjunction with some information I read in the manual. Believe me, I read those paragraphs multiple times just to make sure I understood the concept. Now, you mentioned super high dynamic range lighting and its effect on increased fireflies with unclamped rendering, am I correct to assume that if I use a lower range HDRI under the same conditions I would eliminate most, if not all, fireflies sacrificing some highlighting? This is intriguing and deserves a closer look. Thanks.
