I dubbed this Reshade setting not "photo-realism" but "eyeball mk1" ????
Here are the initial results of observations made at different times of day and different atmospheric conditions. This is of course all made to fit on my screen as watched through my eyes, but still conforming to the DCS standard of 2.2 gamma (thus the name eyeball).
Goal: try to model and design a preset that simulates scattering, reflections, eye adaptation and other eyeball specifics that photography or video are hard to capture. So no photos or videos were used during the tuning of the settings. Just observations. Hope you guys like it.
