I prefer to see the game I am playing. If I want it super dark, I can just turn the lights out at home...

Sorry I'm so late to reply. My life is just such a dizzy whirl of parties and globe-trotting that I find it nearly impossible to keep up!
Anyway, don't get your hopes up about No Tint. One of the reasons I'm looking at Realistic Lighting is that I felt No Tint made dungeons too dark for my taste. I couldn't see a damn thing when I was in Blackreach. I kept walking into columns and railings and off the sides of platforms. Whole areas looked pitch-black to me. I can take that in small doses (in other dungeons there's usually been a dark room, followed by a lighter room that helps to break up the gloom a little bit, or a dark part of an otherwise nicely lit room, ect) but this was just oppressive and unrelenting and finally it got to me. I told myself that I would look for some other alternative when I started my next game.
The reason I think Realistic Lighting might do the trick is something I read in this post of Plutoman's: "...if you want some brighter nights and interiors, just find the brightnessMultiplierNight=1 and change it to 1.1, 1.2, or something like that. Do the same with brightnessMultiplierInterior." That last sentence gives me some hope that fiddling with a value for that line will keep me from having to bring my face up to within an inch of my monitor and squinting into a flat surface composed of various shades of black, near-black, semi-black, faux-black and, every so often, a tiny speck of really dark gray.
